Description
The physics of jet quenching, a generic denomination for the modifications of jets produced in the dense environment of an ultra-relativistic nucleus-nucleus collision, represents one of the main tools at our disposal to experimentally probe the quark-gluon plasma. In this talk, I will discuss recent theoretical breakthrough in our understanding of this physical phenomenon, within the framework of perturbative QCD. My focus will be on the main perturbative mechanisms that drive the modifications of jet observables in heavy-ion collisions, highlighting a new emergent picture for the jet evolution in dense QCD media. As an application of these developments, I will consider the particular case of jet substructure observables, and explain how these techniques can help to pin down specific aspects of the jet dynamics.
