Abstract

Transverse momentum-dependent parton distributions (TMDs) can be formally defined in terms of hadronic matrix elements of quark bilocal operators containing staple-shaped gauge connections. A parametrization of the matrix elements in terms of invariant amplitudes serves to cast them in the Lorentz frame preferred for a lattice calculation. An ongoing program of evaluating TMD observables within Lattice QCD is reviewed, summarizing recent progress with respect to several challenges faced by such calculations. Results on the naively T-odd Sivers and Boer- Mulders effects are presented.
