Signals of Deconfinement Phase Transition and Possible Energy Range of Its Detection

TL;DR

This paper reviews current signals of the deconfinement phase transition, critiques their experimental readiness, and presents new signals suggesting the transition occurs at collision energies of 4.3-4.9 GeV.

Contribution

It introduces new signals of the deconfinement transition based on the hadron resonance gas model, indicating the transition energy range.

Findings

Existing signals are not experimentally verified.

New signals suggest transition at 4.3-4.9 GeV.

Mixed quark-gluon-hadron phase can be reached at these energies.

Abstract

Here we thoroughly discuss the present status of the deconfinement phase transition signals outlined in the NICA White Paper 10.01. It is argued that none of the signals outlined in the NICA White Paper is prepared for experimental verification. At the same time we discuss the new irregularities and new signals of the deconfinement transition found recently within the realistic version of the hadron resonance gas model. All new findings evidence that the mixed quark-gluon-hadron phase can be reached at the center of mass energy of collision 4.3-4.9 GeV.
