arXiv preprint arXiv:2208.05686, 2022•arxiv.orgIn these proceedings, we present the higher-order cumulants of proton multiplicity
distributions of the fixed-target (FXT) run in Au+ Au collisions at $\sqrt {s_ {\rm NN}} $= 3.0
GeV. The cumulant ratios are presented as a function of centrality and collision energy. The
proton cumulant ratio C4/C2 is consistent with fluctuations driven by baryon number
conservation and indicates an energy regime dominated by hadronic interactions. These
data imply that the QCD critical point could exist at energies higher than 3 GeV if created in …
