Event description: 

In heavy-ion collisions, the fragmentation pattern of a high-energy jet is modified by its interactions with the quark-gluon plasma (QGP). Jet substructure observables, i.e. observables build out of the jet constituents, are thus expected to be sensitive to properties of the medium such as its temperature, length or transport coefficients. So far, experimental measurements at RHIC and the LHC have revealed a narrowing of the jet core with respect to proton-proton collisions. In this talk, I will discuss from a theoretical perspective the potential origin of this narrowing with a special focus on color coherence dynamics and propose new observables with enhanced discriminating power that can help confirm or refute state-of-the-art jet quenching models.
