Proton number cumulants and correlation functions at RHIC-BES from hydrodynamics

Abstract

I will present the behavior of proton number cumulants and correlation functions in heavy-ion collisions based on relativistic hydrodynamics, incorporating essential non-critical contributions such as the exact conservation of multiple conserved charges and baryon excluded volume. I will also discuss the resulting constraints on the possible location of the QCD critical point coming from RHIC-BES I data, as well as future perspectives with BES II.
