Lhc Predictions from an Extended Theory with Elastic, Inelastic, and Path Length Fluctuating Energy Loss

We present the LHC predictions for the WHDG model of radiative, elastic, and path length fluctuating energy loss. We find the p⊥ dependence of RAA is qualitatively very different from AWS-based energy loss extrapolations to the LHC; the large p⊥ reach of the year one data at the LHC should suffice to distinguish between the two. We also discuss the importance of requiring a first elastic scatter before any medium-induced elastic or radiative loss occurs, a necessary physical effect not considered in any previous models.
