Description
Jets provide a unique and versatile tool to study different time and energy scales of the strongly interacting matter created in heavy-ion collisions. Here we show, for the first time, a set of jet quenching observables sensitive to the initial stages of heavy-ion collisions. Specifically, we find that in order to reproduce the high-$p_T$ harmonics, the energy loss must be strongly suppressed for the first 0.6 fm of the evolution. This analysis shows the potential of jet observables to constrain the poorly known dynamics of the initial stages of the evolution.
