Quark and gluon TMD correlators in momentum and coordinate space

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-$1\mathrm{/}2$, and spin-$1$ hadrons.
