We will report on current progress in the understanding of the QCD phase diagram, including universal scaling in the chiral limit and the vicinity of the QCD critical point. In the latter case we will discuss the universal scaling of Lee-Yang zeros and their determination from multi-point Pad\'e approximations to the baryon number density at imaginary chemical potentials. In particular, reported results include the critical phase transition temperature, the curvature of the critical and pseudo-critical transition temperature with respect to the chemical potential and the location of the QCD critical point.

  1. Lee--Yang edge singularities in Nonlocal Nambu--Jona-Lasinio Model

    hep-ph 2025-09 conditional novelty 6.0 of 10

    In a nonlocal NJL model, Lee-Yang edge singularities follow trajectories that end at the QCD critical point, with critical exponent 1.494(1) matching mean-field scaling.
