We apply Low's theorem to soft gluon emission from heavy quark scattering in the nonperturbative strongly interacting quark-gluon plasma (sQGP). The sQGP is described terms of dynamical quasiparticles and adjusted reproduce EoS lattice QCD at finite temperature chemical potential. Since emitted long wavelength, it does not provide information on detailed structure scattering, only incoming outgoing partons enough. It simplifies calculations making amplitude factorizable into elastic gluon....

Abstract We review the properties of strongly interacting quark‐gluon plasma (QGP) at finite temperature and baryon chemical potential as created in heavy‐ion collisions ultrarelativistic energies. The description (non‐perturbative) QGP equilibrium is based on effective propagators couplings from Dynamical QuasiParticle Model (DQPM) that matched to reproduce equation‐of‐state partonic system above deconfinement lattice QCD. Based a microscopic transport collisions, we discuss which...

This paper is a write-up of the ideas that were presented, developed and discussed at fourth International Workshop on QCD Challenges from pp to AA, which took place in February 2023 Padua, Italy. The goal workshop was focus some open questions field high-energy heavy-ion physics stimulate formulation concrete suggestions for making progresses both experimental theoretical sides. gives brief introduction each topic then summarizes primary results.
Heavy quark mass in QGP is related to the heavy potential at a large distance. In this study we test three different potentials, namely, free energy, internal energy of pair QGP, and unscreened potential, which was recently proposed by HotQCD Collaboration, through thermal production charm quarks heavy-ion collisions LHC. We find that overestimates LHC, while produces results closest experimental data from ALICE Collaboration among potentials.
