Realistic medium-averaging in radiative energy loss

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 pTpT 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-pTpT suppression, while fluctuations in energy loss with the location of scattering centers weaken the suppression. But, unlike the reduction of v2v2, these effects nearly disappear once αsαs is adjusted to reproduce RAARAA in central collisions
