Finite-size effects on the radiative energy loss of a fast parton in hot and dense strongly interacting matter

Abstract

We consider finite-size effects on the radiative energy loss of a fast parton moving in a finite temperature strongly interacting medium, using the light cone path integral formalism put forward by Zakharov. We present a convenient reformulation of the problem which makes possible its exact numerical analysis. This is done by introducing the concept of a radiation rate in the presence of finite-size effects. This effectively extends the finite-temperature approach of AMY (Arnold, Moore, and Yaffe) to include interference between vacuum and medium radiation. We compare results with those obtained in the regime considered by AMY, with those obtained at leading order in an opacity expansion, and with those obtained deep in the LPM (Landau-Pomeranchuk-Migdal) regime.
