Description
The recent STAR measurements of the higher cumulants of net protons present large deviations from the Poisson baselines and non-monotonic behavior at lower collision energies, indicating the potential of discovery the QCD critical point [1]. In this
talk, I will first introduce our recent investigations on both equilibrium and dynamical critical fluctuations near the QCD critical point. Then, I will show our recent calculations on the thermal (non-critical) fluctuations of (net) charges and (net) protons within the framework of {\tt IEBE-VISHNU} hybrid model, and discuss how various effects such as volume corrections, hadronic scatterings and evolution, resonance decays, as well as realistic centrality cuts and acceptance cuts, etc. influence the thermal fluctuation baselines of (net) charges and (net) protons. \\
