# Critical behavior and net-charge fluctuations from lattice QCD

## TL;DR

This paper reports lattice QCD calculations of critical temperatures and charge fluctuations, providing insights into the QCD phase diagram and the potential location of the critical endpoint.

## Contribution

It offers new lattice QCD results on critical and pseudo-critical temperatures and their implications for the QCD critical endpoint at non-zero baryon chemical potential.

## Key findings

- Critical temperature Tc0=132_{-6}^{+3} MeV
- Implications for cumulants of conserved charge fluctuations
- Insights into the QCD critical endpoint location

## Abstract

We present recent results on the critical and pseudo-critical temperatures in (2+1)-flavor QCD with a physical strange quark mass and two degenerate light quark masses extrapolated to the chiral limit and tuned to the physical value, respectively. We furthermore discuss implication of the observed low chiral phase transition temperature, Tc0=132_{-6}^{+3} MeV, for the structure of cumulants of conserved charge fluctuations at vanishing baryon chemical potential and consequences for the possible location of the QCD critical endpoint in the QCD phase diagram at non-zero baryon chemical potential.
