Light-ray operators, detectors, and OPEs

Abstract: In this talk I will review the recent developments connected to light-ray operators in conformal field theories. Light-ray operators are non-local operators which perform an analytic continuation of the usual local operators in spin. In CFTs they are connected to the recently discovered Lorentzian inversion formula and to some interesting representation theory. Furthermore, they can be interpreted as asymptotic observables, generalizing event shapes such as energy-energy correlators. Finally, I will discuss how they control the small-angle limit of energy-energy correlators.
