QCD thermodynamics with two flavours of Wilson fermions on large lattices

We explore the phase diagram of two flavour QCD at vanishing chemical potential using dy-namical O(a)-improved Wilson quarks. In the approach to the chiral limit we use lattices with a temporal extent of Nt = 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 κ, 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. The 30th International Symposium on Lattice Field Theor
