Fixed point behavior of cumulants in the three-dimensional Ising universality class
《Chinese Physics C》2022年第2期112-121,共10页Xue Pan 
High-order cumulants and factorial cumulants of conserved charges are suggested for the study of the critical dynamics in heavy-ion collision experiments. In this paper, using the parametric representation of the thre...

High cumulants of conserved charges and their statistical uncertainties被引量：2
《Chinese Physics C》2017年第10期98-102,共5页陈丽珠 赵烨印 潘雪 李治明 吴元芳 
Supported by NSFC(11405088,11521064,11647093);Major State Basic Research Development Program of China(2014CB845402);Ministry of Science and Technology(MoST)(2016YFE0104800)
We study the influence of measured high cumulants of conserved charges on their associated statistical uncertainties in relativistic heavy-ion collisions. With a given number of events, the measured cumulants randomly...
