Using next-to-leading order Taylor expansions in baryon chemical potential we find that qualitative features of these ratios closely resemble the corresponding experimentally measured cumulant ratios of net proton-number fluctuations for beam energies down to √sNN?19.6??GeV. We show that the difference in cumulant ratios for the mean net baryon-number, MB/σ2B=χB1(T,μB)/χB2(T,μB), and the normalized skewness, SBσB=χB3(T,μB)/χB2(T,μB), naturally arises in QCD thermodynamics. Moreover, we establish a close relation between skewness and kurtosis ratios, SBσ3B/MB=χB3(T,μB)/χB1(T,μB) and κBσ2B=χB4(T,μB)/χB2(T,μB), valid at small values of the baryon chemical potential.}, title = {Skewness and kurtosis of net baryon-number distributions at small values of the baryon chemical potential}, volume = {96}, year = {2017} }
