【 摘 要 】

Heavy quarks are one of the key tools to study the properties of the expanding plasma created in ultrarelativistic heavy ion collisions. In this context we develop a framework to study the Qq → Qqg collsions in scalar QCD and provide the results for different key quantities. We investigate the radiative energy loss and compare the results to the the collisional energy loss. We conclude that radiative and collisional energy loss together allow for a description of the recently published ALICE data.
