Generalized parton distributions of $\Delta$ resonance in a diquark spectator approach

Abstract

The generalized parton distributions (GPDs) for the spin-3/2 ${\Delta }^{+}$ resonance are studied numerically by using a diquark spectator approach. Our results show that symmetric constraints from time reversal on GPDs are satisfied. The axial vector form factors of the system are also provided and compared with the lattice QCD calculation. Furthermore, the structure functions are obtained from GPDs in the forward limit. The evolution of structure functions to the scales up to 4 GeV are carried out as predictions for the possible lattice QCD calculations.
