Lattice QCD Analysis of Strangeness-Baryon Number Correlations along the Pseudo-Critical Line in (2+1)-Flavor QCD

Lattice QCD calculations show that the ratio of strangeness-baryon number correlation to strangeness fluctuations, χBS 11/χS 2, exhibits moderate changes along the pseudo-critical line in (2+1)-flavor QCD, but differs significantly from preliminary experimental results at lower beam energies in the RHIC beam energy scan.
