Investigating the QCD phase diagram with hadron multiplicities at NICA

TL;DR

This paper explores how NICA's experimental measurements of hadron multiplicities can help map the QCD phase diagram, especially at high baryon-chemical potential, by reviewing current status and outlining future tasks.

Contribution

It proposes a comprehensive approach combining experimental and theoretical efforts to use hadronic abundances as probes of the QCD phase diagram at NICA.

Findings

NICA can effectively investigate the QCD critical line.

Accurate hadron multiplicity measurements are crucial.

The paper identifies key theoretical and experimental tasks.

Abstract

We discuss the potential of the experimental programme at NICA to investigate the QCD phase diagram and particularly the position of the critical line at large baryon-chemical potential with accurate measurements of particle multiplicities. We briefly review the present status and we outline the tasks to be accomplished both theoretically and the experimentally to make hadronic abundances a sensitive probe.
