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 b_T-space, where b_T is Fourier conjugate to the partonic momentum k_T). We consider unpolarized, vector polarized, as well as tensor polarized hadrons, which is relevant for spin-0, spin-1/2, and spin-1 hadrons.
