Form factor decomposition of generalized parton distributions at leading twist

High Energy Physics - Phenomenology 2009-11-10 v1

Abstract

We extend the counting of generalized form factors presented in PRD63(2000) by Ji and Lebed to the axial vector and the tensor operator at twist-2 level. Following this, a parameterization of all higher moments in x of the tensor (helicity flip) operator is given in terms of generalized form factors.
