Findings

Transition temperature T_c determined at fine lattice spacings.

Screening masses computed in various color channels above T_c.

Abstract

We present results of finite temperature QCD from N_f=2 flavors of non-perturbatively improved Wilson fermions on lattices with N_t=8, 10 and 12. The transition temperature T_c is determined for the first time at lattice spacings as low as a = 0.08 fm, albeit at pion masses 1.3 < r_0 m_\pi. We furthermore compute the screening masses in various color channels at T>T_c.
