Jet Substructure Studies from Proton-Proton to Heavy Ion Collisions at the LHC

Jets produced in high-energy collisions serve as invaluable laboratories for QCD. The study of the internal structure of the final fragments inside jets, referred to as jet substructure, has attracted significant interest from both experimentalists and theorists. Jet substructure encapsulates QCD dynamics at various scales, ranging from the initial partonic shower in the weakly coupled limit to hadronization in the strongly coupled regime. In heavy ion collisions, modifications to jet substructure highlight the interplay between jets and the quark-gluon plasma (QGP), offering unique insights into the microscopic properties of the QGP. This presentation will provide a review of recent progress in jet substructure measurements, encompassing proton-proton to heavy ion collisions at the LHC. Additionally, I will discuss prospects for future measurements at both RHIC and the LHC.
