In heavy-ion collision experiments, the study of event-by-event fluctuations is a powerful tool to characterize the thermodynamic properties of the hot and dense QCD matter.
According to the Lattice QCD calculations, a cross-over exists at small μB regions but there is no experimental evidence for the location of predicted cross-over.
Experimentally, it is thought that up to the sixth-order cumulant and its ratio to the variance may be the signal of the cross-over.
The STAR experiment published cumulants up to the fourth-order and cumulant ratios on net-charge.
In addition, the fifth- and sixth-order net-charge cumulants at √sNN = 200 GeV were presented at last Quark Matter for the first time.
This presentation shows updated results of net-charge cumulants from the first- to sixth-order using particle species and pT-dependent efficiency corrections for Au+Au collisions at √sNN= 200 GeV during Beam Energy Scan in 2010 and 2011.
We will discuss centrality dependence of cumulants and experimental results will be compared to Poisson, NBD and UrQMD estimations.
