Our results are relevant for the resummation of Sudakov logarithms for e⁺e⁻ event-shape variables and inclusive hadron-collider observables at next-to-next-to-leading logarithmic accuracy within Soft-Collinear Effective Theory (SCET). Our formalism applies to both SCET-1 and SCET-2 soft functions and we clarify the relation between the respective soft anomalous dimension and the collinear anomaly exponent. We confirm existing two-loop results for about a dozen dijet soft functions and obtain new predictions for the angularity event shape and the soft-drop jet-grooming algorithm.en500 - Science::530 - Physicsarticle10.7892/boris.1221401805.1241410.1016/j.nuclphysb.2018.09.026
