Jets are multiscale objects that provide a direct connection between partons and hadrons, making jet substructure measurements a powerful probe of both perturbative and non-perturbative QCD dynamics. At STAR, a broad set of jet substructure observables, including SoftDrop-groomed observables and N-point Energy Correlators (ENCs), is used to investigate parton shower evolution and hadronization...

50. First unfolded measurement of the jet quenching effect with Z+jet events in PbPb and pp collisions at 5.36 TeV with Run 3 data

The production of jets in association with Z bosons offers a uniquely clean probe of the quark-gluon plasma (QGP), as the Z boson's decay products bypass strong medium interactions, preserving the initial hard-scattering kinematics. We present the latest measurement of Z+jet correlations in the dimuon channel using the new 5.36 TeV Run 3 data collected by the CMS experiment in 2023 and 2024....

In ultra-relativistic heavy-ion collisions, jet yields are suppressed relative to proton–proton baselines due to partonic energy loss in the quark–gluon plasma. This phenomenon, known as jet quenching, reflects the interaction of hard-scattered partons with the hot and dense medium created in the early stages of the collision. This ATLAS contribution presents a set of measurements that go...

70. Bottom-up approach to describe groomed jet data in heavy-ion collisions

The theoretical interpretation of jet observables in heavy-ion collisions is a complex task due to the intricate interplay of perturbative and non-perturbative effects. One way to reduce this complexity is to groom away soft, wide-angle radiation so that perturbative dynamics dominates. Even in this simplified scenario, there are competing explanations for the physical origin of the measured...
