Jet substructure and energy-energy correlators

Studying jets helps us understand quantum chromodynamics (QCD) in high-energy physics, particularly the behavior of quarks and gluons and their confinement in hadrons. This involves the flow of energy within the jets, which is where jet substructure studies are crucial. To better understand key QCD concepts, like asymptotic freedom, we need observables that can be precisely calculated from first principles. Recently, a set of collinear and infrared safe observables has been proposed to describe multipoint energy correlators within jets. With a number of measurements already finalized in pp collisions, our understanding of the perturbative part of the jet shower and the hadronization process has been enhanced. This talk will focus on these results as well as upcoming measurements in heavy-ion collisions where energy correlators may be sensitive to medium response effects at large angles.
