Description
An efficient way to study the QCD phase diagram at small finite density
is to extrapolate thermodynamical observables from imaginary chemical potential.
The phase diagram features a crossover line starting from the
transition temperature already determined at zero chemical potential.
In this talk we focus on the curvature of this line at mu = 0. We present
the extrapolation of the crossover temperature based on three observables
at several lattice spacings. The simulations were performed at
zero and at moderate values of the imaginary chemical potential,
always in the strangeness neutral point. We used the Symanzik-improved
gauge action with four times stout smeared staggered fermions.
