Perturbative renormalization in parton distribution functions using   improved actions
  We calculate the 1-loop renormalization of a set of extended fermionic bilinears which form a basis corresponding to moments of the parton distribution functions.   We use the overlap action for fermions and Luescher-Weisz (LW) action for gluons.   Our results are presented as a function of the overlap parameter rho and the parameters entering the LW action.
