Thermal transition in QCD with Nf =2+1 flavours of Wilson quarks
Mapping out the QCD phase diagram remains one of the outstanding challenges in the theory of the strong interactions. By now, it is well established that the transition along the temperature axis, at vanishing baryon density, is a crossover. This result has been obtained, and confirmed, using simulations of lattice QCD with physical quark masses in the continuum limit, using so-called staggered fermions. Here we show results for Nf = 2 + 1 flavours of Wilson fermion. Observables are compared for two values of the pion mass, focusing on chiral properties for a number of observables.
