Recent lattice QCD results and phase diagram of strongly interacting matter

TL;DR

This paper reviews recent lattice QCD findings related to the equation of state, deconfinement, and hadron contributions in strongly interacting matter, with implications for heavy ion physics and the QCD phase diagram.

Contribution

It provides an updated synthesis of lattice QCD results on the QCD phase diagram, including the role of unobserved hadrons and their impact on thermodynamics and freeze-out conditions.

Findings

QCD equation of state at zero and nonzero baryon chemical potential

Onset of deconfinement for strange and charmed hadrons

Influence of unobserved hadrons on thermodynamics and freeze-out

Abstract

I review recent lattice QCD results on a few selected topics which are relevant to the heavy ion physics community. Special emphasis is put on the QCD equation of state at vanishing and nonzero baryon chemical potential, the onset of deconfinement of open strange and charmed hadrons, the contribution from experimentally not yet observed hadrons to the thermodynamics of the hadronic gas and their influence on freeze-out conditions of strange and light-quark hadrons.
