Rui Wen, Chuang Huang, Wei-jie Fu

摘要:

在2+1味低能有效模型中计算了重子数分布的高阶累积量。量子涨落通过泛函重整化群方法编码。研究了在有限温度和重子化学势下的手征和退禁闭相变。计算了QCD物质的物态方程、重子数涨落和奇异度到六阶,结果与格点量子色动力学的结果一致。

英文摘要:

High order cumulants of the baryon number distribution are calculated in a 2+1 flavor low energy effective model. Quantum fluctuations are encoded through the functional renormalization group approach. The chiral and deconfinement phase transitions are investigated at finite temperature and baryon chemical potential. The equation of state for the QCD matter, fluctuations of the baryon number and the strangeness up to sixth order are calculated, and one finds the results are consistent with those from lattice QCD.
