Description

Energy correlators are infrared-safe collider observables that characterize the flow of energy in scattering events. Originally developed in the context of QCD, they admit a natural operator definition as multi-point correlation functions of the energy flux operator, and provide a common language for collider physics, CFTs, and gravity. I will discuss nonperturbative properties of these observables and methods for constraining them beyond standard perturbation theory. These methods are particularly powerful in conformal field theories, where modern conformal bootstrap techniques apply. In this talk, I will focus on the energy-energy correlator (EEC) in N=4 SYM, where a combination of dispersion relations, integrability, and supersymmetric localization leads to tight two-sided bounds on the EEC at finite coupling and finite rank of the gauge group.
