We determine the second order endpoint of the line of first order phase transitions, which occur in the light quark mass regime of 3-flavour QCD at finite temperature, and analyze universal properties of this chiral critical point. A detailed analysis of Binder cumulants and the joint probability distributions of energy like and ordering-field like observables confirms that the chiral critical point belongs to the universality class of the three dimensional Ising model. From a calculation with improved gauge and staggered fermion actions we estimate that the transition is first order for pseudo-scalar meson masses less than about 200 MeV.

    hep-ph 2025-12 unverdicted novelty 6.0 of 10

    A coupled DSE-FRG-holographic model predicts the QCD critical end point at T_CEP approximately 130-135 MeV and mu_B,CEP approximately 600 MeV, with sensitivity to regulator and normalization choices.

  3. On the nature of the QCD chiral phase transition with imaginary chemical potential

    hep-lat 2025-12 conditional novelty 5.0 of 10

    First-order chiral regions observed on coarse staggered lattices disappear in tricritical points as the lattice spacing decreases at imaginary chemical potential, implying a second-order continuum transition.

  4. Three flavor QCD phase transition with M\"obius domain wall fermions

    hep-lat 2025-01 conditional novelty 5.0 of 10

    A new large-volume lattice QCD run with Möbius domain wall fermions finds the Nf=3 chiral transition at T=121(2) MeV is consistent with a smooth crossover near m_f^MS(2 GeV)=4 MeV.
