abstract

We study the effect of the chiral symmetry restoration (CSR) on heavy-ion collisions observables in the energy range $\sqrt{s_{NN}}$=3-20 GeV within the Parton-Hadron-String Dynamics (PHSD) transport approach. The PHSD includes the deconfinement phase transition as well as essential aspects of CSR in the dense and hot hadronic medium, which are incorporated in the Schwinger mechanism for the hadronic particle production. We adopt different parametrizations of the nuclear equation of state from the non-linear $\sigma-\omega$ model, which enter in the computation of the quark scalar density for the CSR mechanism, in order to estimate the uncertainty in our calculations.

  1. Disentangling Initial-State and Evolution Effects in Heavy-Ion Collisions Using EPOS and PHSD

    hep-ph 2025-09 conditional novelty 5.0 of 10

    By swapping initial conditions and evolution engines between EPOS and PHSD, the authors find that the dynamical evolution stage, not the initial state, dominates final hadron spectra and elliptic flow in 200 GeV Au+Au...

  2. Directed Flow of Protons and Deuterons in Xe+Cs(I) Collisions: Preliminary BM@N Data and THESEUS Modeling

    nucl-ex 2026-08 conditional novelty 4.0 of 10

    Comparing preliminary BM@N proton and deuteron directed flow with THESEUS shows good proton agreement and a slight deuteron overestimation, tentatively supporting thermodynamic light-nucleus formation.
