Description
We present a novel technique for the calculation of the probability for emission of an arbitrary number of gluons radiated from a high-pT probe of the QGP. Our work is an extension of the maximal helicity violating (MHV) method in which the usual soft-collinear factor is classified according to its symmetry under gluon permutations.
For the purposes of illustration, we show the explicit form of the result for from 1 to 4 gluon emissions and present the general expression for any generic $n$ numbers of gluons. In particular, we compute for the first time the QCD corrections to the multi-gluon Poisson approximation. Since all current energy loss calculations assume that the Poisson distribution of photons from QED bremsstrahlung is a good approximation for the multi-gluon radiation in QCD, our results will prove invaluable to leading particle and jet energy loss modellers.
