BES-II data and critical assessment with respect to QCD critical point search

The beam energy scan (BES) program is being pursued in Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) in several stages, the 1st one BES-I at 2010- and the 2nd one BES-II at 2019-, in order to scan the QCD phase diagram and to possibly find and locate the QCD critical point and/or the 1st order phase transition in the high-density area of the phase diagram. In this presentation, recent results on the higher-order netproton fluctuation from the STAR experiment at RHIC and a few other related measurements from other experiments and facilities are shown and discussed by comparing with theoretical expectations with and without including the critical point.
