Jet substructure is a powerful tool to probe the perturbative regime of jet evolution in proton-proton and heavy-ion collisions. Over the past few years, various substructure observables have been proposed to understand specific aspects of jet dynamics in a quark-gluon plasma (QGP).
In this talk, based on [1,2,3], we will explore the ability of such an observable, called Dynamical Grooming,...

Jets are modified as they propagate through the quark-gluon plasma, providing the opportunity to study the properties of the medium, including by measuring modification of the internal jet structure. In this talk, we discuss several recent jet substructure measurements in Pb--Pb collisions at the LHC.

The energy-flow-operator (EFO) provides an idealized field-theoretic definition of a calorimenter. Recently, the angular correlations between EFOs on the celestial sphere have seen a great deal of interest as a tool for jet substructure. Due to the causal structure of EFO correlators, the angular size of the correlations can be viewed as a time parameter: early time perturbative correlations...

The field of jet quenching in heavy ion collisions has been steadily moving towards the description and measurement of jet substructure observables. From a theoretical point of view, the main ingredient to understand how jets evolve inside a medium is still missing: a full evaluation of the in-medium parton splitting with an arbitrary number of scatterings and finite energy fraction. In this...
