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.
