   Properties of quark gluon plasma from lattice calculations

   Peter Petreczky🇺🇸

   I discuss lattice QCD calculations of the properties of strongly interacting matter at finite temperature, including the determination of the transition temperature Tc, equation of state, different static screening lengths and quarkonium spectral functions. The lattice data suggest that at temperatures above 2Tc many properties of the quark gluon plasma can be understood using weak coupling approach, although non-perturbative effects due to static magnetic fields are significant in some quantities.

   Relativistic corrections to the static potential at O(1/m) and O(1/m^2)

   Yoshiaki Koma🇯🇵 · Miho Koma🇩🇪 · Hartmut Wittig🇩🇪

   We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m^2) velocity-dependent potentials, in SU(3) lattice gauge theory. They are important ingredients of potential nonrelativistic QCD for heavy quarkonium. Utilizing the multi-level algorithm, we obtain remarkably clean signals of these potentials up to r=0.9 fm. We observe long range nonperturbative contributions to these corrections.
