The radiation pattern of a QCD antenna in a dense medium
We calculate the radiation spectrum off a q (q) over bar pair of a fixed opening angle theta(q (q) over bar) traversing a medium of length L. Multiple interactions with the medium are handled in the harmonic oscillator approximation, valid for soft gluon emissions. We discuss the time-scales relevant to the decoherence of correlated partons traversing the medium and demonstrate how this relates to
