Abstract

We study transverse momentum dependent parton distribution functions (TMDs) with non‐local operators in lattice QCD, using MILC∕LHPC lattices. We discuss the basic concepts of the method, including renormalization of the gauge link. Results obtained with a simplified operator geometry show visible dipole deformations of spin‐dependent quark momentum densities.
