Anomalous dimension of subleading-power N-jet operators

High Energy Physics - Phenomenology 2018-04-04 v1 High Energy Physics - Theory

Abstract

We begin a systematic investigation of the anomalous dimension of subleading power N-jet operators in view of resummation of logarithmically enhanced terms in partonic cross sections beyond leading power. We provide an explicit result at the one-loop order for fermion-number two N-jet operators at the second order in the power expansion parameter of soft-collinear effective theory.
