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.

    hep-ph 2024-11 conditional novelty 6.0 of 10

    In the large-Nc limit of QCD, the flavor-nonsinglet chiral-odd GPDs E_T and tilde H_T are predicted to obey 2 tilde H_T^{u-d} = -E_T^{u-d} at leading order, with four independent mean-field GPDs including a previously...
