Description

Energy correlators admit a dual description as light-ray operators obeying an operator product expansion on the celestial sphere. I give a pedagogical introduction to the light-ray OPE and its misconceptions, then show that inclusive jet cross-sections are also light-ray measurements. Using the OPE, I derive the small-R jet factorisation theorem, pin down the scaling of hadronisation and higher order corrections, and outline what this framework opens up — including jets at strong coupling.
