Description
An ongoing program of evaluating TMD observables within
lattice QCD is reviewed, summarizing recent progress with
respect to several challenges faced by such calculations.
These lattice calculations are based on a definition of
TMDs through 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. Results presented include data on
the naively T-odd Sivers and Boer-Mulders effects.
