Radiative energy loss results using the Wicks Monte Carlo evaluation of (D)GLV.

Summary

Based on numerical work given in:
Up to and beyond ninth order in opacity: Radiative energy loss with GLV
Simon Wicks

This uses the radiative energy loss formulae from GLV [1] and DGLV [2]. The parameters (temperature, Debye mass, gluon mean free path etc) are set in the same manner as in WHDG. The n=1 version including a (small) jet and gluon mass should be identical to the inelastic only curves in WHDG (up to small variations due to eg possible q integral limits, to be investigated).

Results

Using DGLV (ie including a small mass for the jet and emitted gluon): Q=up, p=10GeV, L=5fm, T=300 MeV, α=.3
