Perturbative renormalization in parton distribution functions using improved actions
Abstract
Description
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.
