Jet quenching in the strongly-interacting quark–gluon plasma

Abstract We propose a hybrid model for medium-induced parton energy loss, in which the hard scales in the process are treated perturbatively, while the soft scales which involve strong coupling dynamics are modeled by AdS/CFT calculations. After fitting a single parameter on R A A for central Au + Au collisions, we are able to predict different observables like R A A and I A A as a function of centrality and reaction plane. We obtain a consistent picture of how jet quenching is modified if the quark–gluon plasma is strongly interacting, and we provide quantitative predictions.
