摘要：

The results on the curvature of a pseudocritical transition line for two-flavor QCD through lattice simulations are presented. The simulations are carried out with Symanzik-improved gauge action and Asqtad fermion action on a lattice 12(3) x 4 at quark mass am = 0.010. At the imaginary chemical potentials a mu(I) = 0.050, 0.150, 0.200, 0.225 and 0.250, we investigate the chiral condensate (psi) over bar psi , plaquette variable P and imaginary part of Polyakov loop Im(L) and their susceptibilities. Analytic continuation from an imaginary chemical potential to a real one is used to obtain the expression for transition temperature as a function of the chemical potential. The curvature is 0.0326(46).
