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 -even, “process-independent” TMDs. Beyond results for -integrated TMDs and quark densities, we present a study of correlations in and . 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 asqtad-improved staggered sea quarks.
