Curvature of the pseudocritical line in QCD: Taylor expansion matches analytic continuation

We determine the curvature of the pseudocritical line of N₅=2+1 QCD with physical quark masses via Taylor expansion in the quark chemical potentials. We adopt a discretization based on stout improved staggered fermions and the tree level Symanzik gauge action; the location of the pseudocritical temperature is based on chiral symmetry restoration. Simulations are performed on lattices with different temporal extent (Nₓ=6, 8, 10), leading to a continuum extrapolated curvature =0. 0145 (25), which is in very good agreement with the continuum extrapolation obtained via analytic continuation and the same discretization, =0. 0135 (20). This result eliminates the possible tension emerging when comparing analytic continuation with earlier results obtained via Taylor expansion.
