DESCRIPTION:Speakers: Prottay Das (National Institute of Science  Educatio
 n and Research (NISER) (IN))\nHadronic resonances are short-lived particle
 s that decay via strong interaction. 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. Recent results on resonance production in Xe--Xe and Pb--Pb collisions 
 at various centre-of-mass energies\, highlighting new results on K*$^{\\pm
 }$(891)\, $\\Sigma$*$^{\\pm}$(1385)\, $\\Xi$*$^{0}$(1820) and $\\Lambda$(1
 520) are presented. The measurements are used to study the system-size and
  collision-energy evolution of transverse momentum spectra\, yields\, mean
  transverse momentum\, yield ratios to long-lived hadrons and nuclear modi
 fication factors. These results are compared to lower energy measurements 
 and model calculations wherever available.\n\nhttps://events.vecc.gov.in/e

DESCRIPTION:Speakers: Sonali Padhan (Indian Institute of Technology Bombay
 )\nHadronic resonances are effective tools for studying the hadronic phase
  in ultrarelativistic heavy-ion collisions. In fact\, their lifetime is c
 omparable to that of the hadronic phase\, and resonances are sensitive to 
 effects such as rescattering and regeneration processes\, which might affe
 ct the resonance yields and shape of the transverse momentum spectra. Thes
 e processes can be studied considering the yield ratio of resonance to the
  corresponding long-lived particle as a function of the charged-particle m
 ultiplicity. Similar characteristics to those in heavy-ion collisions have
  been observed in the multiplicity-dependent studies of particle productio
 n in pp and p--Pb collisions. Resonance measurements may provide insight i
 nto the potential emergence of collective-like phenomena and a non-zero li
 fetime of the hadronic phase in small collision systems.\n\n\n\nIn this co
 ntribution\, we present new ALICE results on the measurement of mesonic an
 d baryonic resonances in small collision systems at LHC energies\, includi
 ng the measurements of  K$^{*\\pm}(892)$\, $\\Lambda(1520)$\, $\\Sigma^{\
 \pm}(1385)$\, $\\Xi^{0}(1530)$\, $\\phi(1020)$ as a function of the charge
 d-particle multiplicity.\n\nhttps://events.vecc.gov.in/event/19/contributi

DESCRIPTION:Speakers: Prottoy Das (Bose Institute (IN))\nThe hard scattere
 d (high $p_{\\rm T}$) partons produced in high energy hadronic and nuclear
  collisions fragment into a collimated spray of final state particles\, kn
 own as jets. Jet properties are sensitive to details of parton showering p
 rocesses and are expected to be modified in the presence of a dense parton
 ic medium. Measurement of intra-jet properties in p-Pb collisions will hel
 p to investigate cold nuclear matter effects and enrich our current unders
 tanding of particle production in such collision systems. In this work\, w
 e will present the measurement of charged-particle jet properties\, the me
 an charged-constituent multiplicity and fragmentation functions for leadin
 g jets in the range of jet $p_{\\rm T}$ from 10 - 100 GeV/$c$ at midrapidi
 ty in p-Pb collisions at 5.02 TeV with ALICE. Results will be compared wit
 h Monte Carlo predictions.\n\nhttps://events.vecc.gov.in/event/19/contribu

DESCRIPTION:Speakers: Souvik Priyam Adhya (IFJ-PAN\, Krakow\, Poland)\nIn 
 this exploratory study\, we investigate the novel scaling features in the 
 jet quenching parameter ($\\hat{q}$) among the static and Bjorken expandin
 g medium profiles for radiative and transverse momentum broadened parton c
 ascades. With these scalings\, firstly\, we study the impact of the sensit
 ivity of the time for the onset of the quenching Bjorken profile as well a
 s the partonic chemistry of the jet fragments on the inclusive jet $R_{AA}
 $ for a purely radiative turbulent cascade. In addition\, we have also stu
 died the effect of the nPDF as well as vacuum like emissions on the jet $R
 _{AA}$. Next\, we study the impact of the expansion of the medium on the r
 apidity dependence of the jet $R_{AA}$  as well as jet $v_2$ and compar
 ing with ATLAS data. Secondly\, we account for the transverse momentum br
 oadening in the cascade to probe the angular structure for hard and soft m
 omentum jets in expanding media. We find that subsequent splittings primar
 ily govern the broadening in comparison to collisional energy loss\, whic
 h could impact the phenomenological description of out-of-cone radiation a
 nd jet quenching in media.\n\nhttps://events.vecc.gov.in/event/19/contribu

DESCRIPTION:Speakers: Kousik Naskar (Institute of Physics\, Bhubaneswar)\n
 The exclusive photoproduction of $\\Upsilon$ and $\\rho$ meson is studied 
 in ultraperipheral pPb collisions at $\\sqrt{s_{NN}} = 5.02$ TeV. The diff
 erential cross-section of $\\Upsilon$ and $\\rho$ meson has been measured 
 as a function of transverse momentum squared $p_{T}^{2}$\, and rapidity $y
 $. The slope of the squared transverse momentum ($p_{T}^{2}$) dependent di
 fferential cross section is extracted to determine the size of the product
 ion region. Also\, we measured the $\\Upsilon$ and $\\rho$ photoproduction
  cross-section as a function of the photon-proton centre-of-mass energies 
 $W_{\\gamma p}$\, which provides valuable information of the gluon distrib
 ution at small values of parton fractional momenta $x$. The results are co
 mpared to various theoretical predictions and to previous measurements.\n\

DESCRIPTION:Speakers: Sinjini Chandra (Variable Energy Cyclotron Centre\, 
 Kolkata)\nThe study of prompt direct photons\, from Compton scattering and
  annihilation hard processes in hadronic collisions\, can test perturbativ
 e quantum chromodynamics theory predictions. In pp collisions\, they can b
 e used to constrain parton distribution functions as they come directly fr
 om the parton-parton hard scatterings. The measurement of direct photon pr
 oduction is complicated due to the presence of large photon background fro
 m hadron decays\, especially from neutral mesons.\n\nIn this contribution\
 , we will present the measurement of isolated photon production in pp coll
 isions at $\\sqrt{s}$ = 8 TeV using the data collected by the ALICE detect
 or. The isolation technique is used to select prompt direct photons and re
 duce contamination from decay and fragmentation photons. The results have 
 been compared to a theoretical prediction.\n\nhttps://events.vecc.gov.in/e
