We propose a novel approach to investigate the evolution of jets in heavy-ion collisions by employing a combination of jet substructure measurements. Our method focuses on isolating the perturbative regime of jet evolution. As a proof of concept, we analyze the distribution of the hardest splitting above a transverse momentum scale, $k_{t,{\rm cut}}$, in high-$p_T$ jets. For a $k_{t,{\rm...
Energy-Energy Correlators are a class of jet structure observables that has gained notoriety in recent years. These observables are designed and built from foundational concepts in field theory such as energy fluxes at varying resolution scales and are therefore a direct test of theoretical concepts with experimental measurements. With results from pretty much every experimental...
Energy correlators have been measured in heavy-ion collisions for the first time this year. We present a theoretical description and interpretation of the two-point energy correlator in the collinear limit of inclusive heavy-ion jet samples. Specifically, we focus on describing the effects of selection bias due to energy loss, which manifests as a shift in the transition region of the...
