摘要:The fourth-order correlations of conserved charges, such as the baryon number, electric charge, and strangeness, are studied at finite temperature and nonzero baryon chemical potential in an effective model. It is found that the fourth-order correlations change rapidly and have three extrema during the chiral crossover with the increase of the baryon chemical potential. The absolute values of the extrema approach infinity when the thermodynamical system moves toward the QCD critical point and the fourth-order correlations are divergent at the critical point. The contour plots of the fourth
