Abstract: (APS)

We determine the curvature of the pseudocritical line of strong interactions by means of numerical simulations at imaginary chemical potentials. We consider Nf=2+1 stout improved staggered fermions with physical quark masses and the tree level Symanzik gauge action, and explore four different sets of lattice spacings, corresponding to Nt=6,8,10,12, in order to extrapolate results to the continuum limit. Our final estimate is κ=0.0135(20).
