Perturbative renormalization in parton distribution functions using Overlap fermions and Symanzik improved gluons
نویسنده
چکیده
We calculate the 1-loop renormalization of the fermion self-energy, all local fermion bilinears, as well as a set of extended bilinears which form a basis corresponding to moments of the parton distribution functions. We use the overlap action for fermions and Symanzik improved action for gluons. Our results are presented as a function of the overlap parameter ρ and the parameters entering the Symanzik action.

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 ρ and the parameters entering the LW action.
متن کاملOne-loop renormalisation of quark bilinears for overlap fermions with improved gauge actions
We compute lattice renormalisation constants of local bilinear quark operators for overlap fermions and improved gauge actions. Among the actions we consider are the Symanzik, Lüscher-Weisz, Iwasaki and DBW2 gauge actions. The results are given for a variety of ρ parameters. We show how to apply mean field (tadpole) improvement to overlap fermions. The question, what is a good gauge action, is ...
متن کاملNon-perturbative renormalization of the quark condensate in Ginsparg-Wilson regularizations
We present a method to compute non-perturbatively the renormalization constant of the scalar density for Ginsparg-Wilson fermions. It relies on chiral symmetry and is based on a matching of renormalization group invariant masses at fixed pseudoscalar meson mass, making use of results previously obtained by the ALPHA Collaboration for O(a)-improved Wilson fermions. Our approach is quite general ...
متن کاملNucleon parton distributions in the large N c limit ∗
We review recent progress in calculating the twist–2 parton distribution functions (PDF's) at a low normalization point in the large–N c limit, where the nucleon can be described as a soliton of the effective chiral lagrangian. This field–theoretic approach preserves all general requirements on the PDF's (positivity, normalization etc.). In particular, it allows to calculate the polarized and u...
متن کاملRenormalization of Bilinear Quark Operators for Overlap Fermions
We present non-perturbative renormalization constants of fermionic bilinears on the lattice in the quenched approximation at β = 6.1 using an overlap [1] fermion action with hypercubic(HYP)blocked links. We consider the effects of the exact zero modes of the Dirac operator and find they are important in calculating the renormalization constants of the scalar and pseudoscalar density. The result...
