Description
Lattice QCD calculations of parton distribution functions have so far been restricted
to only their first few Melin moments. Broken rotational symmetry on the lattice introduces unavoidable power divergent mixing of lattice twist-2 matrix elements of different spin that obscures the continuum limit. Here I discuss new options that either avoid power divergent mixing or allow us to perform the subtractions that are needed in order to obtain higher moments.
