Transverse momentum dependent (TMD) distribution correlators can beparametrized in terms of TMD parton distribution functions (PDFs), or TMDs forshort. We provide an overview of the leading-twist quark and gluon TMDs, bothin 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 forspin-$0$, spin-$1/2$, and spin-$1$ hadrons.
