Abstract
Abstract We present results from a jet energy loss calculation using the Gyulassy-Levai-Vitev (GLV) formalism and bulk medium evolution from the covariant transport MPC. At both RHIC and LHC energies we find that realistic transverse expansion strongly reduces elliptic flow at high p T compared to calculations with transversely “frozen” profiles. We argue that this is a generic feature of GLV energy loss. Transverse expansion also leads to stronger high- p T suppression, while fluctuations in energy loss with the location of scattering centers weaken the suppression. But, unlike the reduction of v 2 , these effects nearly disappear once α s is adjusted to reproduce R A A in central collisions.
