Heavy Quarkonia in Quark-Gluon Plasma
, 2005 Using the color-singlet free energy F_1 and total internal energy U_1 obtained by Kaczmarek et al. for a static quark Q and an antiquark Qbar in quenched QCD, we study the binding energies and wave functions of heavy quarkonia in a quark-gluon plasma. By

Relaxation time for strange quark spin in rotating quark-gluon plasma [PDF]
Physical Review C, 2019 Experiments at the Relativistic Heavy Ion Collider (RHIC) have measured the net polarization of $\Lambda$ and $\bar{\Lambda}$ hyperons and attributed it to a coupling between their spin and the vorticity of the fluid created in heavy ion collisions ...

Heavy Quarkonium States With Baryonic Chemical Potential
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

On Extracting Thermal Parameters and Scenario in High‐Energy Collisions
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.The inconsistent thermal parameters derived from various models in high‐energy collisions are examined. A comprehensive literature review suggests model‐independent parameters to address these inconsistencies, based on the average transverse momentum 〈pT〉 and root‐mean‐square transverse momentum pT2.

Lattice study of the electromagnetic conductivity of the quark-gluon plasma in an external magnetic field [PDF]
, 2019 We study the electromagnetic (e.m.) conductivity of QGP in a magnetic background by lattice simulations with $N_f = 2+1$ dynamical rooted staggered fermions at the physical point.

On the Square Speed of Sound in High‐Energy Collisions: Range of Values and How to Understand It
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.After reviewing the sound speeds in various forms and conditions of matter, we investigate the sound speed of hadronic matter that has decoupled from the hot and dense system formed during high‐energy collisions. We comprehensively consider factors such as energy loss of the incident beam, rapidity shift of leading nucleons, and the Landau hydrodynamic

Photons from strange-quark annihilation in a quark-gluon plasma [PDF]
, 2006 We compute the energy spectrum of photons which originate from the quark-annihilation process ss¯→γg in quark-gluon plasma. The spectrum peaks at an energy Eγmax∼2ms∼400 MeV in the rest frame of the plasma.
