Properties of the QGP created in heavy-ion collisions

TL;DR

This paper reviews the properties of the quark-gluon plasma created in heavy-ion collisions, focusing on its non-perturbative characteristics, modeling approaches, and the observables that reveal its formation and properties.

Contribution

It introduces a comprehensive review of the QGP properties using the Dynamical QuasiParticle Model and discusses how microscopic transport models connect to experimental observables.

Findings

QGP properties are modeled using the DQPM matched to lattice QCD data.

Certain observables in heavy-ion collisions are sensitive to the QGP formation.

The review highlights the importance of non-perturbative effects in QGP behavior.

Abstract

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