Abstract

We present a general analytical expression for the fixed-order structure of the distribution of a generic non-global observable with the k_t 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.
