Abstract
We present charm and bottom nuclear modification factors for RHIC and LHC using Standard Model perturbative QCD and recent AdS/CFT string drag energy loss models. We find that extreme extrapolations to LHC mask potential experimentally determinable differences in the individual s but that their ratio, as a function of transverse momentum is a remarkably robust observable for finding deviations from either theoretical framework.
