Abstract

The nuclear modification factor RAA has been satisfactorily described by various jet quenching models. Nonetheless, all these formalisms, until very recently, underpredicted the high-pT (> 10 GeV) elliptic flow v2. We find that the simultaneous description of these observables requires to strongly suppress the quenching for the first ~ 0.6 fm after the collision. This shows the potential of jet quenching observables to constrain the dynamics of the initial stages of the evolution.
