Recent results on conserved charge fluctuations in ALICE

Abstract:

Recent results on the analysis of event-by-event net-baryon number fluctuations in Pb–Pb collisions at $\sqrt{s_{NN}} = 2.76$ $\sqrt{s_{NN}} = 2.76$ sNN−−−√=2.76 and 5.02 TeV are presented. The cumulants of the net-proton distributions, proxies for the net-baryon distributions, up to third order are discussed. The experimental results are compared with HIJING and EPOS model calculations and the dependence of fluctuation measurements on the phase-space coverage is addressed in the context of calculations from Lattice QCD (LQCD) and the Hadron Resonance Gas (HRG) model.
