Comparing parton energy loss models
arXiv:1012.2261 · doi:10.1016/j.nuclphysa.2011.02.020
Abstract
The similarities and differences between three commonly used formalisms for radiative parton energy loss in hot strongly interacting matter are discussed. The single gluon emission spectra are evaluated for a model system consisting of a homogeneous medium with a fixed length, the `TECHQM brick'. Sizable quantitative differences are found and the origins of these differences are discussed.
