QCD thermodynamics with two flavours of Wilson fermions on large lattices

Understand

We explore the phase diagram of two flavour QCD at vanishing chemical potential using dynamical O(a)-improved Wilson quarks.

• In the approach to the chiral limit we use lattices with a temporal extent of N_t=16 and spatial extent L=32,48 and 64 to enable the extrapolation to the thermodynamic limit with small discretisation effects.
• In addition to an update on the scans at constant \kappa, reported earlier, we present first results from scans along lines of constant physics at a pion mass of 290 MeV.
• We probe the transition using the Polyakov loop and the chiral condensate, as well as spectroscopic observables such as screening masses.
