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

Understand

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.
