abstract
Emphasizing the importance of renormalization in the context of thermal field theory in general, it is pointed out that the Debye mass in the hot quark gluon plasma is determined by the coupling at the scale $m_D$, not $T$ as commonly presumed. The mended result agrees quantitatively with lattice QCD calculations in the strong coupling regime almost down to $T_c$.

Heavy quark suppression and anisotropic flow at intermediate momentum
Heavy quark suppression and elliptic flow in noncentral heavy-ion collisions are computed with a unified collisional plus radiative energy-loss model, showing a collisional-to-radiative transition and weaker pT dependence from radiation.
