The dynamic structure of the density fluctuation without the presence of the magnetic field shows three Lorentzian peaks. The central Rayleigh peak is surrounded by two Bri llouin peaks symmetrically situated around the Rayleigh peak. But with the presence of an external constant magnetic field\, the structure factor sh ows four peaks identified as one Rayleigh peak\, two Brillouin peaks\, and one peak due to the coupling of the magnetic field with the fluid velocit y. The emergence of the extra peak due to the coupling can play an importa nt role in measuring the relaxation of the system.\n\nhttps://events.vecc. gov.in/event/19/contributions/852/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/852/ END:VEVENT BEGIN:VEVENT SUMMARY:Relativistic dissipative hydrodynamics with BGK collision kernel DTSTART;VALUE=DATE-TIME:20230210T100000Z DTEND;VALUE=DATE-TIME:20230210T101500Z DTSTAMP;VALUE=DATE-TIME:20260907T212223Z UID:indico-contribution-106-878@events.vecc.gov.in DESCRIPTION:Speakers: Pracheta Singha (Bose Institute)\nRelativistic dissi pative hydrodynamics is an efficient tool to explore the collective behavi or of strongly interacting QGP (Quark Gluon Plasma) medium produced in hea vy-ion collision experiments. 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 BEGIN:VEVENT SUMMARY:Charm quark momentum broadening in a non-equilibrium glasma DTSTART;VALUE=DATE-TIME:20230210T094500Z DTEND;VALUE=DATE-TIME:20230210T100000Z DTSTAMP;VALUE=DATE-TIME:20260907T212223Z UID:indico-contribution-106-931@events.vecc.gov.in DESCRIPTION:Speakers: Harshit Pandey (IMSc)\nOne of the outstanding proble ms in thermal QCD is to understand how and whether the heavy quarks produc ed in the early stages thermalize in the medium formed in a heavy-ion coll ision (HIC). Recent sets of experimental data point to the fact that charm quarks show the same collectivity as light quarks. In this study\, we per form classical-statistical lattice simulations for relativistic charm (rep resenting a Dirac particle)\, to compute the momentum broadening and real- time spectral functions of heavy quarks in the presence of strongly popula ted gauge fields\, as they exist in the early non-equilibrium stage of HIC s.\n\nhttps://events.vecc.gov.in/event/19/contributions/931/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/931/ END:VEVENT BEGIN:VEVENT SUMMARY:Model study of directed flow of light flavor hadrons\, resonances and light nuclei DTSTART;VALUE=DATE-TIME:20230210T093000Z DTEND;VALUE=DATE-TIME:20230210T094500Z DTSTAMP;VALUE=DATE-TIME:20260907T212223Z UID:indico-contribution-106-812@events.vecc.gov.in DESCRIPTION:Speakers: Tribhuban Parida (IISER Berhampur)\nDirected flow is understood to be sensitive to the initial conditions of heavy ion collis ions and is used to constrain the initial matter profile. However\, in the present study we have shown the importance of the $v_1$ of resonances and light nuclei which probes some additional physics of heavy ion collisions . We have proposed a model for the initial energy and net-baryon density w hich is able to describe the directed flow($v_1$) of light flavor hadrons and the observed $v_1$ splitting between baryons and anti-baryons. Inorder to probe the effect of hadronic stage on $v_1$\, we have calculated the d irected flow of resonances like $K^{*0}$ and observed a dominant effect du e to the rescattering of $K^{*0}$ with the pion rich medium. More interest ingly\, we have observed that the directed flow of deuteron and triton whi ch are sampled thermally from the freezeout hypersurface has different tre nd as compared to the deutron and triton obtained from coalscence model. W ith the model calculation of deuteron and triton $v_1$\, we will demonstra te the relevance of quark coalescence model. Further\, the effect of criti cal equation of state on the $v_1$ of identified particles and on the spli tting between baryon and anti-baryon directed flow will be discussed.\n\nh ttps://events.vecc.gov.in/event/19/contributions/812/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/812/ END:VEVENT BEGIN:VEVENT SUMMARY:Statistical hadronization model for low-energy heavy-ion collision s DTSTART;VALUE=DATE-TIME:20230210T091500Z DTEND;VALUE=DATE-TIME:20230210T093000Z DTSTAMP;VALUE=DATE-TIME:20260907T212223Z UID:indico-contribution-106-776@events.vecc.gov.in DESCRIPTION:Speakers: Radoslaw Ryblewski (Institute of Nuclear Physics Pol ish Academy of Sciences)\nWe show that the transverse mass and rapidity sp ectra of protons and pions produced in Au-Au collisions at sNN=2.4 GeV can be well reproduced in a thermodynamic model assuming a single-freeze-out scenario of particles from a spheroidally symmetric hypersurface. This sce nario corresponds to a physical picture used by Siemens and Rasmussen in t he original formulation of the blast-wave model used commonly at RHIC and LHC energies. Our framework extends this approach by incorporating a Hubbl e-like expansion\, flow asymmetry with respect to the beam direction\, and resonance decays. With the model parameters determined by the hadronic ab undances and spectra\, we make further predictions of the pion HBT correla tion radii that turn out to be in qualitative agreement with the measured ones. Altogether\, our results bring evidence for substantial thermalizati on of the matter produced in heavy-ion collisions in the few-GeV energy re gime and its spheroidal expansion.\n\nhttps://events.vecc.gov.in/event/19/ contributions/776/ LOCATION:Hall 1 (Sapphire) URL:https://events.vecc.gov.in/event/19/contributions/776/ END:VEVENT BEGIN:VEVENT SUMMARY:Does the hadronic phase of relativistic nuclear collisions feature a hydrodynamic regime?

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 END:VCALENDAR
