The QCD crossover line in a finite volume
We compute the crossover line of strongly interacting matter in the temperature (T) - baryo-chemical potential ( µ B ) plane of the QCD phase diagram. We use large scale lattice QCD simulations at vanishing µ B to solve the path integral in the transition regime between T = 120 and 200 MeV. We introduce a high order Taylor scheme for the Polyakov loop and extract the static quark entropy. The peak position of the latter defines the transition line that we can extract up to 400 MeV in µ B . For the simulations the 4HEX staggered action was used with 2+1 flavors at physical quark masses.
