abstract

The energy-energy correlation in electron-positron annihilation was one of the first infrared-safe QCD observables. It has now been computed through next-to-next-to-leading order (NNLO) in the strong coupling, and through NLO analytically for arbitrary angular separation. Large logarithms can be resummed for small angles and near the back-to-back limit, potentially allowing for an improved measurement of the strong coupling. Similar observables can be defined at the LHC and can serve as computable, infrared-safe jet substructure variables.
