摘要：
Naive, leading order, fully strongly-coupled AdS/CFT energy loss models are either falsified or put into significant doubt when constrained by RHIC and then compared to LHC data. The proper inclusion of fluctuations in heavy quark momentum loss leads to LHC predictions, constrained by RHIC, not in qualitative disagreement with measurements. Once renormalized, strong-coupling energy loss predictions for jet suppression with a new, physically motivated jet definition within AdS/CFT yields predictions in surprisingly good agreement with preliminary LHC results.
