Abstract
We present a general analytical expression for the fixed-order structure of the distribution of a generic nonglobal observable with the kt jet algorithm at any perturbative order. This novel formulation is obtained within the framework of the eikonal approximation, assuming strong-energy ordering of emitted partons. The proposed formula is applicable to a wide range of processes at both lepton and hadron colliders. Published by the American Physical Society2025
