LHC Predictions from an extended theory with Elastic, Inelastic, and Path Length Fluctuating Energy Loss

摘要

We present the LHC predictions for the WHDG model of radiative, elastic, andpath length fluctuating energy loss. We find the pT dependence of RAA isqualitatively very different from AWS-based energy loss extrapolations to theLHC; the large pT reach of the year one data at the LHC should suffice todistinguish between the two. We also discuss the importance of requiring afirst elastic scatter before any medium-induced elastic or radiative lossoccurs, a necessary physical effect not considered in any previous models.
