Quark and gluon TMD correlators in momentum and coordinate space
arXiv:1612.06585
Abstract
Transverse momentum dependent (TMD) distribution correlators can be parametrized in terms of TMD parton distribution functions (PDFs), or TMDs for short. We provide an overview of the leading-twist quark and gluon TMDs, both in momentum space and in coordinate space (also called -space, where is Fourier conjugate to the partonic momentum ). We consider unpolarized, vector polarized, as well as tensor polarized hadrons, which is relevant for spin-, spin-, and spin- hadrons.
