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.
