Abstract
We discuss in detail a method to study transverse momentum dependent parton distribution functions (TMDs) using lattice QCD. To develop the formalism and to obtain first numerical results, we directly implement a bilocal quark-quark operator connected by a straight Wilson line, allowing us to study T-even, “process-independent” TMDs. Beyond results for x-integrated TMDs and quark densities, we present a study of correlations in x and k⊥. Our calculations are based on domain wall valence quark propagators by the LHP Collaboration calculated on top of gauge configurations provided by the MILC Collaboration with Nf=2+1 asqtad-improved staggered sea quarks.
