TMD gluon distributions for multiparton processes

High Energy Physics - Phenomenology 2020-07-22 v3

Abstract

We derive gauge invariant operators entering definitions of the Transverse Momentum Dependent (TMD) gluon distributions, for all five and six parton processes. Our calculations utilize color decomposition of amplitudes in the color flow basis. In addition, we find the general result for multi-gluon process (with arbitrary number of gluons) at large NcN_{c}. On phenomenological ground our results may be used for multi-jet production in the small-xx regime, where the TMD gluon distributions can be derived from the Color Glass Condensate effective theory.
