This phenomenon can be studied using lattice QCD techniques and the most p opularly used fermion discretization\, the staggered fermions only have a remnant of the full chiral symmetry of QCD\, which is (perturbatively) bel ieved to be recovered in the continuum limit. We for the first time study the eigenvalue distribution of the QCD Dirac operator with highly improved staggered quark discretization as a function of three different lattice s pacings across the crossover transition temperature $T_c$\, and perform th e continuum extrapolation. From the features of the eigenvalue spectrum\, we can conclude that though the flavor non-singlet part of the chiral symm etry is restored above $T_c$ the flavor singlet $U_A(1)$ part of it remain s broken. Moreover\, we observe a level repulsion between the infrared eig envalues is quadratic to the spacing similar to the Gaussian unitary ensem ble(GuE) of chiral random matrix theory\, unlike the near-zero modes. The consequences of these findings will be discussed.\n\nhttps://events.vecc.g ov.in/event/19/contributions/826/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/826/ END:VEVENT BEGIN:VEVENT SUMMARY:Surface effects on hydrodynamic evolution DTSTART;VALUE=DATE-TIME:20230207T091500Z DTEND;VALUE=DATE-TIME:20230207T093000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-771@events.vecc.gov.in DESCRIPTION:Speakers: P S Saumia ()\nWe study the effect of surface tensio n of the phase boundary in the dynamics of an expanding fluid.

Latt ice QCD is also used at small baryon densities using Taylor expansion of p ressure. The agreement between QMHRG and Lattice QCD for pressure and seco nd order chiral susceptibility is good. However there are significant dif ferences between QMHRG and Lattice prediction of higher order susceptibili ties. Also at finite density the difference are significant. This suggests importance of non-resonant interactions in QCD thermodynamics. Also the m ost appropriate hadronic model that describes the confined phase of QCD sh ould be ubiquitous\, irrespective of the thermodynamic conditions.\n\n We have chosen hadronic models which are well constrained from the neutron star merger data and nuclear matter properties. We have calculated susceptibilities upto fourth order subject to constraints $n_Q/n_B=0.4\, n_S=0$ and $\\mu_Q=\\mu_S=0$. Comparision with Lattice Data at finite dens ity shows repulsive interactions due to omega meson play important role in bridging the gap between QMHRG and Lattice QCD. This is an alternative ap proach to VDW-HRG models where repulsion is introduced using phenomenologi cal parameters. \n \n Using energy density of QCD crosso ver transition at zero baryon density\, attempt has also been made to expl ore the phase diagram of QCD.

Due to this they are typically produced in hard scatt ering processes\nwith large Q2 and thus offer a unique perspective to stud y the transition from quark to\nhadrons in all collision systems. The late st measurements of charm meson and baryon\nproduction in pp collisions all owed the first measurement of the total charm production cross\nsection in cluding the contribution of all ground-state charm hadrons and the first\n measurement of the fragmentation fractions of charm in hadrons in pp colli sions. The\nmeasurement of the charm baryon-to-meson yield ratios show a s ignificant increase with\nrespect to the measurements performed in e+e− and ep collisions\, which suggests that the\nfragmentation of charm is not universal across different collision systems. Thus\, precise\nmeasurement s of charm baryon and meson production are crucial to study the charm quar k\nhadronization in a partonic rich environment like the one produced in p p collisions at the\nLHC energies.

It results in the production of the strong coherent gluon fields known as Glasma. The colored electric and magnetic fields evolve by the means of Classical Yang-Mills (CYM) equa tions. The lifetime of this pre-equilibrium stage is of the order of forma tion and thermalization time of Quark-Gluon Plasma (QGP)\, typically a sho rt fraction of fm/c.\n\nHeavy quarks (HQs) produced in the early phase of the ultra-relativistic heavy-ion collisions are efficient probes each for the pre-equilibrium Glasma phase and the equilibrated quark-gluon plasma. We study the diffusion of the HQs in the evolving Glasma (EvGlasma) using Wong’s equations. We compare the transverse momentum broadening\, $\\sig ma_p$ of the HQs in the evolving Glasma fields with that of a standard\, M arkovian-Brownian motion in a thermalized medium with the same energy dens ity of the Glasma fields. We observe that the $\\sigma_p$ of HQs increases non-linearly during the very early time in the Glasma\, suggesting heavy quarks super-diffuse in the gluon fields. We also find that for a smaller value of saturation scale\, $Q_s$\, the average transverse momentum broade ning is approximately the same for the two cases\, but for a larger value of $Q_s$\, Langevin dynamics underestimates the $\\sigma_p$. Adding to thi s\, we are also studying the anisotropic angular momentum flow of HQs in t he Glasma\, and we present some preliminary interesting results.\n\nhttps: //events.vecc.gov.in/event/19/contributions/769/ LOCATION:Hall 2 (Crystal) URL:https://events.vecc.gov.in/event/19/contributions/769/ END:VEVENT BEGIN:VEVENT SUMMARY:Heavy-flavour production measurements in pp and Pb-Pb collisions i n ALICE DTSTART;VALUE=DATE-TIME:20230207T094000Z DTEND;VALUE=DATE-TIME:20230207T095500Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-893@events.vecc.gov.in DESCRIPTION:Speakers: Shreyasi Acharya (LPC\, FRance)\nOpen heavy-flavour hadrons are one of the the key diagnostic tools available to study the den se\, hot strongly interacting matter formed in relativistic heavy-ion coll isions. The charm and beauty quarks are produced at the early stages of th e collision via hard scattering due to their large bare masses\, which exc eed the QCD scale parameter ($\\lambda_{\\text{QCD}}$) significantly. In p p collisions\, where a hot and strongly interacting medium is not expected to be formed\, the measurement of heavy-flavour production serves as a re ference for heavy-ion collision studies\, and provides a crucial testing g round for pQCD models\, and for understanding hadronization mechanisms in vacuum. Multiplicity dependent measurements in pp collisions\, are also va luable tools to investigate the hadronization mechanisms and characterize multiparton interactions.

However\, the reason behind the almost instantaneous unpinning of a larg e number of vortices still needs a proper mechanism. We proposed that the neutron-vortex scattering in the inner crust of a pulsar may be responsibl e for such vortex unpinning. The strain energy released by the crustquake is assumed to be absorbed in some part of the inner crust. It causes pair- breaking quasi-neutron excitations from the existing free neutron superflu id in the bulk of the inner crust. The scattering of these quasi-neutrons \nwith the vortex core neutrons should unpin a large number of vortices fr om the thermally affected regions and result in pulsar glitches. We consid er a few geometries of the affected pinning region to study the implicatio ns of the vortex unpinning in the context of pulsar glitches. We find that a Vela-like pulsars \ncan release about $\\sim 10^{11} - 10^{13}$ vortice s by this mechanism and results in glitches of size $\\sim 10^{-11} - 10^{ -9}$. We also explored the possibility of a vortex avalanche triggered by the movement of the unpinned vortices. An estimate of the glitch size caus ed by an avalanche shows a favorable result.

Due to their large mass\, they do not thermalize with the constituents of the quark-gl uon plasma (QGP) over the lifetime of the plasma. Hence\, they witness the entire evolution of QGP and are effective probes to study the strongly in teracting matter. We study the heavy quark transport coefficients (drag an d momentum diffusion) for collision and radiative processes\, using pertur bative QCD and kinetic theory for viscous QCD medium. The thermal medium e ffects are incorporated through the effective fugacity quasiparticle model \, based on the lattice QCD equation of state. The effective modelling of the QCD medium as quasiparticles with encoded in-medium interactions modif ies the momentum distribution function of the QGP constituent particles\, i.e. light quarks\, anti-quarks\, and gluons by the introduction of a temp erature-dependent effective fugacity parameter. Viscous corrections to hea vy quark transport coefficients due to shear and bulk viscosities of the m edium are incorporated at first-order in the thermal distribution function by solving the effective Boltzmann equation within relaxation time approx imation.

In the presence of the Higgs\, the Eucli dean action breaks the Z_3 symmetry explicitly. The determination of the s trength of explicit breaking requires integration of the matter fields. We carry out this using lattice Monte Carlo simulations\, near the confineme nt-deconfinement transition. The partition function averages of observable s that are sensitive to the Z_3 symmetry\, i.e the Polyakov loop\, gauge H iggs interaction terms etc. show that the strength of Z_3 explicit breakin g decreases steadily with the lattice cut-off\, and is possibly vanishingl y small in the continuum limit.

This w ork studies various applications of machine learning tools in the physics of heavy-ion collisions. One of the crucial initial state observables\, th e impact parameter\, plays a vital role in establishing the initial state effects\, which subsequently affects the final state observables in heavy- ion collisions. However\, measurement of this quantity is almost impossibl e in experiments. Thus\, we propose to use ML-based regression models such as the gradient boosting decision trees (GBDT) to obtain a prediction of impact parameter in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV u sing a multiphase transport model (AMPT). We also estimate an event shape observable\, transverse spherocity from experimentally available final sta te observables using the same GBDT model. The regression model trained wit h the minimum bias data is shown to predict the centrality-wise transverse spherocity distributions. Another direction is the possible use of deep l earning techniques for the event-by-event elliptic flow estimation in RHIC and LHC energies. The ability of deep learning models to learn unique pat terns and correlations from data to map highly complex non-linear function s is a matter of interest. A novel method is proposed to feed the track-le vel kinematic information as input to the deep neural network (DNN). The m odel is trained with Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV minimum bias simulated events. All charged hadrons are considered for the training. The trained model is successfully applied to estimate the centra lity dependence of $v_2$ for both RHIC and LHC energies. Also\, the propos ed model is quite successful in predicting the transverse momentum ($p_{\\ rm T}$) dependence of $v_2$ as well. This work is being extended to estima te the elliptic flow of pions\, kaons\, and protons and study the scaling properties of $v_2$. Results of the DNN estimator are compared to both sim ulation and experiment\, which concludes the robustness and prediction acc uracy of the model.\n\nhttps://events.vecc.gov.in/event/19/contributions/8 53/ LOCATION:Hall 2 (Crystal) URL:https://events.vecc.gov.in/event/19/contributions/853/ END:VEVENT BEGIN:VEVENT SUMMARY:Correlation of dynamical density fluctuation in magnetic field DTSTART;VALUE=DATE-TIME:20230210T101500Z DTEND;VALUE=DATE-TIME:20230210T103000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-852@events.vecc.gov.in DESCRIPTION:Speakers: Mahfuzur Rahaman (Darjeeling Government College)\nTh e correlation of dynamical density fluctuation has been investigated withi n the scope of the Mueller-Israel-Stewart theory.

In the first case we have dealt wi th wave functions of the Schroedinger equation corresponding to various qu arkonia species where as for the later one\, we have considered the stoc hastic average of the same . A precise comparison of these two aspects has been presented. We realise that our method is an approximate way to analy se the short time behaviour of quarkonium in real valued potential and for long time behaviour one must adopt a non perturbative technique for solvi ng schr\\"odinger equation of quarkonium bound states in evolving QGP. On the other hand the perturbation technique seems to be valid enough to deal with the same for a complex valued quark anti-quark potential when it is dealt with the stochastic average of wave functions only.\n\nhttps://event s.vecc.gov.in/event/19/contributions/874/ LOCATION:Main Hall (Coral) URL:https://events.vecc.gov.in/event/19/contributions/874/ END:VEVENT BEGIN:VEVENT SUMMARY:Re-visiting the $J/\\Psi$ suppression for quark-gluon plasma forma tion in small systems DTSTART;VALUE=DATE-TIME:20230210T103000Z DTEND;VALUE=DATE-TIME:20230210T104500Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-825@events.vecc.gov.in DESCRIPTION:Speakers: Ananta Prasad Mishra ()\nThere have been different p roposals for signatures of the formation of a deconfined thermal medium(qu ark-gluon plasma) in heavy-ion collisions. The suppression of $J/\\Psi$ in the deconfined medium is one of the cleanest signals among many other sig natures like elliptic flow\, jet quenching etc. for the formation of the d econfined medium. However\, there are very few signals effective for the f ormation of QGP in small systems such as the systems produced in proton-pr oton\, proton-deuteron and deuteron-deuteron collisions. Here the medium formed is shown to be very short-lived compared to that formed in heavy io n collision as the system undergoes 3-dimensional spherical expansion from the very beginning of the hydrodynamic phase. We model the dynamics of th e small systems for different sizes of the formed systems after the Gubser flow model and we infer that the hydrodynamic expansion phase timescale i s smaller by a factor of at least 2. We then calculate the dissociation pr obability of $J/\\Psi$ through the non-adiabatic evolution of the state us ing the time-dependent perturbation theory for different values of thermal ization time. We find rather small dissociation probability of $J/\\Psi$ i n small systems in contrast to that in the systems produced in Au-Au/Pb-Pb collisions\, thereby establishing that quarkonia($J/\\Psi$) suppression m ay not be a very useful signature for the formation of the thermal medium for proton-proton/proton-deuteron or deuteron-deuteron collisions.\n\nhttp s://events.vecc.gov.in/event/19/contributions/825/ LOCATION:Hall 2 (Crystal) URL:https://events.vecc.gov.in/event/19/contributions/825/ END:VEVENT BEGIN:VEVENT SUMMARY:Higher-order quark and gluon propagators in thermal medium DTSTART;VALUE=DATE-TIME:20230210T071500Z DTEND;VALUE=DATE-TIME:20230210T073000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-873@events.vecc.gov.in DESCRIPTION:Speakers: Najmul Haque (NISER\, India)\nBare perturbative resu lts at finite temperatures have some serious problems\, infrared sensitivi ty of the massless gauge theories\, gauge-dependent damping rates\, etc. A dditionally\, QCD thermodynamics are poorly convergent if truncated order- by-order in the coupling constant.

These properties are the impact parameter\, the eccentricity\, and the participant eccentricity. Although ML techniques have been used previously to determine the impact parameter of these collisions\, we study multiple ML algorithms\, their error spectr um\, and sampling methods using exhaustive parameter scans and ablation st udies to determine a combination of efficient algorithm and tuned training set. This gives multifold improvement in accuracy for all three different heavy-ion collision models. The three models chosen are a transport model \, a hydrodynamic model\, and a hybrid model. The motivation for using thr ee different heavy-ion collision models was to show that even if the model is trained using a transport model\, it gives accurate results for a hydr odynamic model as well as a hybrid model. We show that the accuracy of the impact-parameter prediction depends on the centrality of the collision. W ith the standard application of ML training methods\, prediction accuracy is considerably low for central collisions. We have improved the accuracy by using different sampling techniques.

Experiments conduct ed in the last decade to search for the CME in heavy-ion collisions have b een inconclusive. The RHIC's isobar program was implemented in an effort to resolve this issue. In addition\, a new technique for investigating the CME called the Sliding Dumbbell Method (SDM) [1] has been developed. This approach looks at each individual event to determine the back-to-back ch arge separation. The SDM facilitates the selection of events corresponding to various charge separations ($f_{DbCS}$) across the dumbbell. A partiti oning of the charge separation distributions for each collision centrality into ten percentile bins is done in order to find potential CME-like even ts corresponding to the highest charge separation across the dumbbell.\nIn this contribution\, the results based on CME sensitive $\\gamma$-correlat or ($\\gamma = \\langle \\cos(\\phi_a+\\phi_b - 2\\Psi_{RP}) \\rangle$) wi ll be discussed for each bin of $f_{DbCS}$ in each collision centrality fo r isobaric collisions (Ru+Ru and Zr+Zr) at $\\sqrt{s_{\\mathrm{NN}}} = 200 $ GeV measured with the STAR detector. The background contribution due to statistical fluctuations is obtained by randomly shuffling the charges of the particles in a particular collision centrality. The correlated backgr ound is calculated for each $f_{DbCS}$ bin of charged shuffled events usin g their corresponding original events.\n\n**References**\n[1] J. Singh\, A. Attri\, and M. M.

It was shown that these bound states\, particularly bottommoniu m\, dissociate in the QGP medium due to the color screening of the real po tential and scattering with the thermal constituents known as Landau dampi ng\, also responsible for developing the imaginary part of the potential. While efforts have been made to explore the quarkonium suppression in the static limit\, i.e.\, $\\omega\\rightarrow 0$\, effects arising from the f inite frequency region of the gluon spectral function remains less explore d.\n\nIn view of this\, we investigate the finite frequency effects by usi ng the full gluon spectral function on the quarkonium dissociation. To stu dy the singlet octet transitions\, we first implement lattice-motivated me dium-modified potential for the singlet states and evaluate the bound stat e wavefunction and the corresponding binding energy at each temperature. F or the octet states\, we work in the two limiting cases of the Debye scree ning. First\, we consider no screening and take repulsive Coulomb potentia l for the octet state. Second\, we assume complete screening and take free wave functions. We further investigate contributions from the pole of the propagator as well as Landau damping in 1S and 2S states. In particular\, we quantitatively compare the contributions arising from pole and Landau damping for the realistic values of temperature.\n\nhttps://events.vecc.go v.in/event/19/contributions/809/ LOCATION:Hall 2 (Crystal) URL:https://events.vecc.gov.in/event/19/contributions/809/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent ALICE results on light-flavor production and minimum-bias p hysics DTSTART;VALUE=DATE-TIME:20230210T060000Z DTEND;VALUE=DATE-TIME:20230210T062500Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-1012@events.vecc.gov.in DESCRIPTION:Speakers: Sushanta Tripathy ()\nhttps://events.vecc.gov.in/eve nt/19/contributions/1012/ LOCATION:Hall 2 (Crystal) URL:https://events.vecc.gov.in/event/19/contributions/1012/ END:VEVENT BEGIN:VEVENT SUMMARY:Anisotropic structure of heavy quarkonium potential in presence of magnetic field DTSTART;VALUE=DATE-TIME:20230210T100000Z DTEND;VALUE=DATE-TIME:20230210T101500Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-851@events.vecc.gov.in DESCRIPTION:Speakers: Ritesh Ghosh ()\nSeveral heavy-ion collision experim ents at RHIC and LHC have been performed in identifying quark-gluon plasma (QGP) matter. In recent times\, non-central heavy-ion collisions are of m ore interests where very strong magnetic field is produced in the directio n perpendicular to the reaction plane. Many theoretical efforts have been made to study the modification of the strongly interacting matter in prese nce of an external magnetic field.\n\nThe heavy quarkonium is one of the i mportant probes to investigate the properties of nuclear matter in presenc e of finite temperature and magnetic field. Also the time scale of quarkon ia formation and the magnetic field generation are of similar order. So th e study of heavy quarkonia in presence of magnetic field is of great inter est.\nIn this work we have explored the imaginary part of the Heavy Quark (HQ) potential and subsequently the dissociation of heavy quarkonia at fin ite temperature and magnetic field. With respect to earlier investigations on this topic\, present work contain three new ingredients. First one is considering all Landau level summation\, for which present work can be app licable in entire magnetic field domain - from weak to strong. Second one is the general structure of the gauge boson propagator in a hot magnetized medium\, which is used here in heavy quark potential problem first time. Third one is a rich anisotropic structure of the complex heavy quark poten tial\, which explicitly depends on the longitudinal and transverse distanc e.

We suggested a technique of probing the phases by studying the effects of phase transition induced density fluctuations on pulse profile modulation. Such density fluctuation s cause the initial moment of inertia tensor of an oblate shape pulsar (wi th the pulsar deformation parameter $\\eta$) to get random additional cont ributions for each component. These contributions are assumed to be Gaussi an distributed with certain width characterized by the strength of density fluctuations $\\epsilon$. Using sample values of $\\epsilon$ and $\\eta$\ , we solve Euler's equations for the rotational dynamics of the pulsar to observe the effects of wobbling through the modifications of pulse profile s. Our results show a specific pattern in the perturbed pulses\, which are observable in modulations of pulses over a large period. Once the density fluctuations fade away\, leading to a uniform phase in the interior of th e pulsar\, the off-diagonal components of the MI tensor also \nvanish\, ev entually causing the wobbling of the pulsar to die away. This feature allo ws one to distinguish these transient pulse modulations from the effects o f any initial wobbling. Since the decay of these modulations in time is di rectly related to the relaxation of density fluctuations in the pulsar\, i t gives valuable information about the nature of phase transition occurrin g inside the pulsar.\n\nhttps://events.vecc.gov.in/event/19/contributions/ 900/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/900/ END:VEVENT BEGIN:VEVENT SUMMARY:Initial state physics in relativistic heavy-ion collisions DTSTART;VALUE=DATE-TIME:20230208T033000Z DTEND;VALUE=DATE-TIME:20230208T040000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-987@events.vecc.gov.in DESCRIPTION:Speakers: Raju Venugopalan ()\nhttps://events.vecc.gov.in/even t/19/contributions/987/ LOCATION:Main Hall (Coral) URL:https://events.vecc.gov.in/event/19/contributions/987/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for the critical point of strongly interacting matter by NA 61/SHINE at the CERN SPS DTSTART;VALUE=DATE-TIME:20230210T071500Z DTEND;VALUE=DATE-TIME:20230210T073000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-890@events.vecc.gov.in DESCRIPTION:Speakers: Haradhan Adhikary (Jan Kochanowski University)\nThe existence and location of the QCD critical point is an object of both expe rimental and theoretical studies.

It is believed that asymptoticall y free quark-gluon plasma came into existence after a few microseconds of the "Big bang" when energy and matter densities were enormously high. The essential characteristic of the strongly interacting quarks-gluons plasma phase is collective behavior. Observations in various heavy-ion collisions at RHIC and LHC energies have exhibited such demeanor. The other observat ions\, like strangeness enhancement\, also support the existence of quark- gluon plasma in heavy-ion collisions. In comparison\, the sight of QGP in $p+p$ collisions is ignored so far due to the lack of particle number dens ity in $p+p$ collisions. Thus over the decades\, the $p+p$ collision syste m served as a baseline for heavy-ion collisions and helped reveal the unco nventional behavior of the heavy-ion collisions. In contrast to that\, rec ently\, collective behavior and strangeness enhancement have been observed in $p+p$ collisions at the LHC energies. These observations suggest that the existence of a QGP-like medium in small systems cannot be ruled out co mpletely if collision energy is large enough. Inspired by these observatio ns\, we attempt to investigate the existence of a QGP-like medium in $p+p$ collisions through charmonia suppression at $\\sqrt{s} = $ 5.02\, 7\, and 13 TeV collisions energies. We employ 1+1D second-order viscous hydrodyna mics to obtain the temperature cooling law for the QGP medium evolution. F urther\, we use the Unified Model of Quarkonia Suppression (UMQS) to expla in the experimental data available corresponding to normalized charmonium yield $\\left(\\frac{dN_{J/\\psi}/d\\eta}{}\\right)$ with respect to the n ormalized charged-particle multiplicity $\\left(\\frac{dN_{ch}/d\\eta}{}\\ right)$. Our UMQS model contains possible QGP effects such as color screen ing\, collisional damping\, and gluonic dissociation\; these effects reduc e the quarkonia yield in ultrarelativistic collisions.

Resonances having a lifetime comparab le to that of the hadronic phase (phase between chemical and kinetic freez e-out) are subject to regeneration and rescattering occuring in this phase \, which lead to the modification of their yields and spectral shapes. Bot h these competing effects decide the final yield of the resonances at kine tic freeze-out surface. The measured resonance yields depend on their life time\, the hadronic interaction cross section of their decay products\, an d the hadronic phase lifetime. \\\\\n\nRescattering and regeneration can b e studied via the yield ratio of resonance to the\ncorresponding long-live d particle with the same quark content as a function of system size\, whic h is compared with model predictions with and without hadronic interaction s.

The formation of QGP is often characterized by a phenomenon called strangenes s enhancement where the production of strange-to-non-strange particles are enhanced relative to peripheral or proton-proton interactions. Besides th e enhancement in K/π ratios\, a non-monotonic energy dependence was also reported for Λ̄ to p̄ ratios at CERN SPS\, attributed to a signature fo r the strangeness enhancement . As anti-particles are produced directly fr om the reaction\, the Λ̄/ p̄ ratios are considered as a cleaner probe f or the strangeness enhancement. However\, at this energy range hadronic in teractions are dominant and\, particularly for Λ̄ and p̄\, processes li ke baryon-anti-baryon (BB̄) annihilation can significantly modify final y ields and spectral shape which may lead to an apparent enhancement in the Λ̄/p̄ ratios. In this work\, we use UrQMD hadronic transport model\, to investigate the role of baryon-anti-baryon (BB̄) annihilation on Λ\, Λ ̄ hyperon production and its effect on Λ̄/p̄ ratios. The UrQMD calcula tions with BB̄ annihilation can produce the trend of average transverse m ass spectra for Λ and Λ̄\, as well as\, the characteristic enhancement in Λ̄/p̄ ratios in data as a function of centrality and collision energ y. Furthermore\, Λ̄/p̄ ratios extracted from the feed-down corrected SP S data are in good agreement with UrQMD model calculations with BB̄ annih ilation. This suggests that Λ̄/p̄ enhancement can not be interpreted as a direct signature for strangeness enhancement and BB̄ annihilation has a significant role to play.\n\nhttps://events.vecc.gov.in/event/19/contrib utions/934/ LOCATION:Main Hall (Coral) URL:https://events.vecc.gov.in/event/19/contributions/934/ END:VEVENT BEGIN:VEVENT SUMMARY:Taming instabilities in relativistic hydro and magneto hydro.

They u ndergo rescattering and regeneration within the hadronic phase\, which mod ifies their yields. The dynamics of these particles\, especially the $K^*( 892)^0$ meson\, and thus varying yields have been used extensively to stud y the hadronic phase lifetime. In this work\, we explore the applicability of hydrodynamics in the hadronic phase using the Knudsen number ($Kn$). F urther\, we employ 1+1D second-order viscous hydrodynamics for the evoluti on of hadronic medium and to obtain the hadronic phase lifetime. The evolu tion is assumed to break down when the limit\, $Kn > 1$\, is attained. It is assumed that the particle yield gets preserved at this limit. The obtai ned lifetime is then used within a transport model for $K^*(892)^0$ mesons modelled by including rescattering and regeneration effects to predict th eir final state yield. The results obtained in our calculations are qualit atively in agreement with the experimentally obtained hadronic phase lifet ime and $K^*(892)^0/K$ ratio.\n\nhttps://events.vecc.gov.in/event/19/contr ibutions/787/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/787/ END:VEVENT BEGIN:VEVENT SUMMARY:Understanding rapidity dynamics in heavy ion collisions DTSTART;VALUE=DATE-TIME:20230208T123000Z DTEND;VALUE=DATE-TIME:20230208T130000Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-993@events.vecc.gov.in DESCRIPTION:Speakers: Sandeep Chatterjee ()\nhttps://events.vecc.gov.in/ev ent/19/contributions/993/ LOCATION:Main Hall (Coral) URL:https://events.vecc.gov.in/event/19/contributions/993/ END:VEVENT BEGIN:VEVENT SUMMARY:Particle identification in LHC Run 3 pp collisions at $\\sqrt{s}$= 13.6 TeV using the ALICE TPC and TOF detectors DTSTART;VALUE=DATE-TIME:20230207T094000Z DTEND;VALUE=DATE-TIME:20230207T095500Z DTSTAMP;VALUE=DATE-TIME:20260721T004434Z UID:indico-contribution-19-1013@events.vecc.gov.in DESCRIPTION:Speakers: Banajit Barman (Gauhati Universtiy)\nThe study of th e strongly-interacting matter will benefit from larger data samples that w ill be collected in Run 3\, thanks to major upgrades of the ALICE detector s. The main focus will be on rare probes and the study of observables that were not accessible with previous data. The LHC Run 3 has started and pp collisions at the unprecedented centre-of-mass energy of $\\sqrt{s} = 13.6 $ TeV have been recorded. The ALICE Collaboration has collected approxima tely 20 pb$^{-1}$ of minimum-bias pp collision events\, which correspond t o about 30 times more data than that collected in Run 2. In November 2022\ , a sample of about 1 million Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 5.36 TeV has also been collected. These high-quality data will be used in a pre liminary phase for the characterization of the new detectors and calibrati ons.\n\nIn this talk\, the performance regarding particle identification w ith the ALICE Time Projection Chamber and Time-Of-Flight detectors using a newly developed analysis framework will be presented. The results of this work will be compared with that of Run 2 to assess the quality of the new data and of the detector calibrations.

This effective theory relies on some necess ary microscopic inputs and relativistic kinetic theory often serves as the source. Within this statistical framework the dissipative quantities can be expressed in terms of the out of equilibrium phase space distribution f unctions\, employing the Boltzmann equation. The Relaxation Time Approxima tion (RTA) simplifies the incorporation of the microscopic interaction to the Boltzmann equation via a single parameter known as relaxation time. Ho wever\, as an artifact of this simplification\, one needs additional match ing conditions to satisfy the conservation laws of energy-momentum and num ber current. In this work\, we have derived the relativistic dissipative h ydrodynamics from a more general Bhatnagar-Gross-Krook (BGK) approximation which converges to the RTA description as a limiting case. The BGK kerne l conserves the number current by construction and thus no specific matchi ng condition for the same is necessary. This additional freedom leads to a class of physically consistent hydrodynamic descriptions constrained by a single matching condition ensuring energy-momentum conservation. This fra mework provides a platform to explore the effects of general matching cond itions on transport coefficients and their deviation from the usual RTA pr escription. We have also proposed a modified BGK collision kernel which ca n be particularly useful for systems with vanishing net baryon density and derived relativistic dissipative hydrodynamics from it.\n\nhttps://events .vecc.gov.in/event/19/contributions/878/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/878/ END:VEVENT END:VCALENDAR
