Energy loss in a partonic transport model including bremsstrahlung processes

Understand

A detailed investigation of the energy loss of gluons that traverse a thermal gluonic medium simulated within the perturbative QCD--based transport model BAMPS (a Boltzmann approach to multiparton scatterings) is presented in the first part of this work.

• For simplicity the medium response is neglected in these calculations.
• The energy loss from purely elastic interactions is compared to the case where radiative processes are consistently included based on the matrix element by Gunion and Bertsch.
• From this comparison gluon multiplication processes gg -> ggg are found to be the dominant source of energy loss within the approach employed here.
