Fluctuations of conserved quantities are predicted to be sensitive observables to probe the QCD phase transition and critical point in heavy-ion collisions. Experimentally, various cumulants (up to fourth order) of net-proton (proxy for net-baryon (B)), net-kaon (proxy for net-strangeness (S)), and net-charge (Q) multiplicity distributions of Au+Au collisions at √sNN = 7.7 ~ 200 GeV has been measured by the STAR and PHENIX experiments from the first phase of beam energy scan program at the Relativistic Heavy Ion Collider. In this paper, i will discuss those experimental results and the corresponding physics implications.
