First mapping of the QCD critical surface in full (T, μ_B, μ_Q, μ_S) space via constant-entropy expansion gives a critical point at (114, 602) MeV in the pure baryon direction, with μ_B,c shifting 40-100 MeV in strangeness-neutral directions while remaining similar in charge-neutral ones.

First measurements of pT correlations in Au+Au collisions at 3-7.7 GeV reveal non-monotonic energy dependence in central events with 5 sigma significance, breaking 1/sqrt(N_part) scaling.
Lattice QCD yields first-principles splitting ratios for chemical potentials in Ru+Ru vs Zr+Zr collisions that are comparable in size to Bayesian STAR extractions, with Δμ_Q negative, Δμ_S positive, and only moderate magnetic-field dependence.
JAM model simulations with the new CIGAR framework compute proton cumulants at √sNN = 3.2-4.5 GeV as a non-critical baseline for QCD critical point searches.
The study analyzes temperature dependence of Lee-Yang zeros and edge singularities in a finite-volume mean-field QCD model and compares finite-size scaling methods for identifying the critical point.
A review of lattice QCD findings on the finite-temperature QCD transition at zero baryon chemical potential, its chiral limit behavior, constraints on the phase boundary and critical endpoint at finite density, plus advances under external fields and conditions.
Recent net-proton cumulant ratios from RHIC BES-II data are compared to non-critical models from Lattice QCD, HRG, hydrodynamics and UrQMD, with volume fluctuation effects noted at fixed-target energies.
