Abstract

We determined the curvature of the phase transition line in the µ-T plane using a Taylor expansion in µ. The Polyakov loop and the strange quark number susceptibility were measured to locate the pseudocritical line. The analysis was carried out on N_t = 4,6,8,10 lattices generated with a Symanzik improved gauge and stout-link improved (2+1) flavour staggered fermion action using physical quark masses.
