Ratio of charm to bottom R_AA as a test of pQCD vs. AdS/CFT energy loss
Abstract
Description
LHC predictions for the charm and bottom nuclear modification factors using pQCD and AdS/CFT drag energy loss models are given. We show that a new observable, the double ratio of charm to bottom nuclear modification factors, allows for easy experimental distinction between the two classes of energy loss models.
