Abstract:High order cumulants of the baryon number distribution are calculated in a 2+1 flavor low energy effective theory. 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 and the kurtosis of the baryon number distribution are calculated in the low energy effective theory, and one finds the results are consistent with those from lattice QCD.
