Description
Results based on a generic dE/dx-model that interpolates between running coupling pQCD based models such as CUJET2.0 and AdS/CFT-inspired holographic prescriptions are compared to recent data on the high-pT pion nuclear modification factors and the high-pT elliptic flow in nuclear
collisions at RHIC and LHC. The jet-energy loss models are coupled to state-of-the-art viscous hydrodynamic fields. The impact of energy-loss fluctuations, event-by-event fluctuations, viscosity, and different colliding systems is discussed. While RHIC data are found to be surprisingly consistent with most dE/dx+Hydro models, extrapolations to
LHC energies favor running coupling QCD-based energy-loss models, while conformal holography models are shown to be inconsistent with the data.
