Higher moments (kurtosis (κ), skewness (S) and variance (σ 2)) of multiplicity distributions are sensitive to the correlation length and can be used to search for the QCD critical point. The moment products κσ 2 and S σ of net-proton distributions, which are also related to volume independent baryon number susceptibility ratios, can be compared with Lattice QCD and Hadron Resonance Gas (HRG) model calculations. We discuss the recent progress in the higher moments analysis of net-protons multiplicity distributions.
