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 rst numerical results,we directly ...

Form factors of the nucleon have been extracted from experiment with high precision. However,
lattice calculations have failed so far to reproduce the observed dependence of form factors on
the mome...
