Description

The recent net-proton fluctuation results of the STAR experiment from the beam energy scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC) have drawn much attention to explore the QCD critical point and the nature of the deconfinement phase transition. The non-monotonic behavior of $\kappa\sigma^{2}$ around $\sqrt{s_{NN}}$ = 19.6 GeV in the STAR results even increased the excitement in the field, as it may be associated with the existence of a QCD critical point. Although the presence of many statistical fluctuations become the background for the dynamical fluctuations and it is important to disentangle and identify them to have a correct interpretation. In this presentation we will demonstrate our recent findings for the stopped proton fluctuations and event-pile up scenarios as a background and their influence on the interpretation of net-proton fluctuations.
