Show affiliationsThe gluon and quark collisional widths in hot QCD plasmas are discussed with emphasis on temperatures near Tc, where the coupling is large. Considering the effect on the entropy, which is known from lattice calculations, it is argued that the width of the partons, which in the perturbative limit is given by γ ~ g2ln(g−1)T, should be sizeable at intermediate temperatures but has to be small close to Tc. This behaviour implies a substantial reduction of the radiative energy loss of jets near Tc.
