Description

We investigate the radiative break-up of a highly energetic quark or gluon in a high-temperature QCD plasma. We find that, as a result of the turbulent nature of the underlying parton cascade the quark to gluon ratio of the soft fragments tends to a universal constant value that is independent of the initial conditions, within an inertial range of momenta T ≪ ω ≪ E, where E denotes the energy of the original hard parton (jet) and T the temperature of of the medium. We discuss implications of this result to jet quenching physics and the problem of thermalization of the quark-gluon plasma in heavy ion collisions.
