Dynamical screening away from equilibrium: hard photon production and collisional energy loss
arXiv:hep-ph/9809214
Abstract
We investigate the production rate for hard real photons and the collisional energy loss in the quark-gluon plasma away from chemical equilibrium. Applying the Hard-Thermal-Loop resummation scheme away from equilibrium, we can show that Landau damping provides dynamical screening for both fermion and boson exchange present in the two quantities.
