Towards the N_f=2 deconfinement transition temperature with O(a) improved Wilson fermions

Understand

A lot of effort in lattice simulations over the last years has been devoted to studies of the QCD deconfinement transition.

• Most state-of-the-art simulations use rooted staggered fermions, while Wilson fermions are affected by large systematic uncertainties, such as coarse lattices or heavy sea quarks.
• Here we report on an ongoing study of the transition, using two degenerate flavours of nonperturbatively $\Ord(a)$ improved Wilson fermions.
• We start with $N_{t}=12$ and 16 lattices and pion masses of 600 to 450 MeV, aiming at chiral and continuum limits with light quarks.
