In the search of QCD phase boundary and critical point, higher-order cumulants of conserved quantities are proposed as promising observables and have been studied extensively both experimentally and theoretically. In this paper we present cumulant ratios up to 6th-order of net-proton number distributions in Au+Au collisions at √SNN = 7.7 - 200 GeV from STAR Beam Energy Scan program phase I and √S = 200 GeV p + p collisions. The results are compared with various models and Lattice QCD calculations.
