DESCRIPTION:Speakers: Eduardo Garnacho Velasco (Bielefeld University)\nThe
  interplay between quantum anomalies and electromagnetic fields leads to a
  series of non-dissipative transport effects in QCD\, such as the Chiral M
 agnetic Effect and the Chiral Separation Effect\, among others. In this wo
 rk we study anomalous transport phenomena with lattice QCD simulations usi
 ng improved staggered quarks in the presence of a background magnetic fiel
 d. In particular\, we calculate the conductivities both in the case of fre
 e fermions and in full QCD\, analyzing the dependence of these coefficient
 s with several parameters\, such as the temperature and the quark mass\n\n

DESCRIPTION:Speakers: Sanatan Digal (The Institute of Mathematical Science
 s)\nWe study the effect of Higgs in the fundamental representation\, on Z_
 3 symmetry in SU(3)-Higgs theory. 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. Simultaneously the strength of the confine
 ment-deconfinement transition grows stronger. These results suggest that s
 imilar studies in QCD are necessary to determine the explicit breaking of 
 Z_3 symmetry in the QGP-hadron transition. For small explicit breaking Z_3
  meta-stable states are expected near the transition and may be relevant f
 or heavy-ion collisions.\n\nhttps://events.vecc.gov.in/event/19/contributi

DESCRIPTION:Speakers: Pushpa Panday (Indian Institute of Technology Roorke
 e)\nWe have studied the momentum transport coefficients\, viz. shear and b
 ulk viscosity\, in a weakly magnetized ($eB\\ll T^2$) deconfined thermal Q
 CD medium at finite quark chemical potential ($\\mu$). The magnetic field 
 generates anisotropy in the medium\, causing the previously isotropic scal
 ar transport coefficients to become anisotropic and separate into several 
 components. Depending upon the direction of the magnetic field and current
 \, we can have three possible components\, namely\, longitudinal\, transve
 rse\, and Hall.\nWe have obtained five shear ($\\eta_0\,\\eta_1\,\\eta_2\,
 \\eta_3$ and $\\eta_4$) and two bulk viscous components ($\\zeta_0$ and $\
 \zeta_1$) using relativistic Boltzmann transport equation under relaxation
  time approximation. Interaction among partons is incorporated through the
  quasiparticle mass of quarks and gluons ($T$\, $\\mu$\, $B$ dependent)\, 
 calculated using one-loop perturbative thermal QCD.\n \n \n  It is observe
 d that the magnetic field acts differently on left (L) and right (R)-hande
 d chiral modes of quark. This leads to the lifting of degeneracy in mass o
 f those modes\, in contrast to the strong magnetic field case ($eB>>T^2$)\
 , where the modes are degenerate. The magnetic field dependence of L and R
  modes of $\\eta_0\, \\eta_1$ and $\\eta_3$ is opposite in nature\, viz. t
 he L mode magnitude decreases whereas the R mode magnitude increases\, wit
 h the magnetic field. This is in contrast to $\\eta_2$ and $\\eta_4$\, for
  which\, both the L and R mode magnitudes increase with the magnetic field
 . The L modes of both $\\zeta_0$ and $\\zeta_1$ show an increment with mag
 netic field for the entire temperature range.  For the R mode\, up to $T \
 \sim 0.35 \\mathrm{GeV}$\, the magnitude at $e B=0.2 m_\\pi^2$ is greater 
 than at $e B=0.1 m_\\pi^2$\; beyond $T \\sim 0.35 \\mathrm{GeV}$\, the mag
 nitude at $e B=0.1 m_\\pi^2$ becomes greater than that at $e B=0.2 m_\\pi^
 2$. Also\, these shear and bulk viscosities get amplified with quark chemi
 cal potential for both modes. Additionally\, we have also examined the eff
 ects of\nthe magnetic field on specific shear and bulk viscosities\, Prand
 tl number\, and Reynolds number for L and R modes over a given temperature
  range.\n\nhttps://events.vecc.gov.in/event/19/contributions/856/

DESCRIPTION:Speakers: Rajkumar Mondal (VECC\, Kolkata)\nThe rate of dilept
 on production is calculated from a hot magnetized hadronic medium in the f
 ramework of real time formalism of finite temperature field theory. The pr
 incipal component in dilepton production is the thermo-magnetic spectral f
 unction of $\\rho^0$ obtained by solving the Dyson-Schwinger equation. Thi
 s is followed by evaluating the one loop self-energy of $\\rho^0$ containi
 ng thermo-magnetic propagators of charged pion in the loop. The study of a
 nalytic structure of thermo-magnetic spectral function shows that there is
  a non-trivial yield in dileption production in low invariant mass region 
 due to the fact that charged pions occupy different Landau levels before a
 nd after scattering of $\\rho^0$ in addition to the usual contribution com
 ing from Unitary cut beyond two pions threshold. This is purely magnetic f
 ield effect.\n\nhttps://events.vecc.gov.in/event/19/contributions/940/

DESCRIPTION:Speakers: JAGBIR SINGH (PANJAB UNIVERSITY\, CHANDIGARH)\nThe c
 hiral imbalance along with the magnetic field produced during heavy-ion co
 llisions may cause a charge separation in the magnetic field direction\, a
  phenomenon known as the chiral magnetic effect (CME). 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\,
