Lattice QCD at finite temperature: some aspects related to chiral symmetry

TL;DR

This paper reviews lattice QCD studies at finite temperature focusing on chiral symmetry, including the chiral condensate, meson screening masses, and baryon and meson masses near the crossover.

Contribution

It highlights recent lattice QCD results related to chiral symmetry restoration and hadron properties at high temperatures.

Findings

Chiral condensate acts as an approximate order parameter.

Meson screening masses increase near the crossover.

Baryon and meson masses, including D(s), are affected by temperature.

Abstract

Out of the many exciting results obtained with the lattice approach to QCD under extreme conditions, I discuss a few selected items related to chiral symmetry: the chiral condensate as an approximate order parameter, meson screening masses, and masses of baryons and mesons, including D(s) mesons, when approaching the crossover from the hadronic side.
