Description
Beyond leading power there are interesting new phenomena that can be investigated in the realm of transverse momentum dependent (TMD) distribution functions, probed with processes like semi-inclusive DIS and Drell-Yan. In this talk I discuss the subleading power TMD factorization for these processes, including their dependence on novel distribution functions known as quark-gluon-quark ($qgq$) correlators, which probe new aspects of TMD hadron structure. I discuss all-order definitions for renormalized $qgq$ correlators, which both cancel novel and standard rapidity divergences, and only depend on one hadronic state. I also discuss matching calculations and renormalization group evolution for these distributions.
