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.

  1. Finite-volume analysis and universal scaling signatures near the chiral phase transition in (2+1)-flavor QCD

    hep-lat 2025-08 conditional novelty 5.0 of 10

    New finite-volume lattice data for the subtracted chiral condensate agree with 3-d O(2) scaling for H<=1/160, while larger H violates the universal curve.

  2. Quark mass dependence of a QCD critical point and structure of the Columbia plot

    hep-ph 2025-07 conditional novelty 5.0 of 10

    In a truncated Dyson-Schwinger setup, the QCD critical point moves to higher temperature and lower baryon chemical potential as light quark masses decrease toward the chiral limit.
