The numerical study of the generalized parton distributions (GPDs) for the spin-3/2 A+ resonance is conducted using a diquark spectator approach. The results confirm the satisfaction of symmetric constraints from time reversal on GPDs. The axial-vector form factors and the structure functions are also analyzed and compared with lattice QCD calculations. The scale evolution of the structure functions up to 4 GeV are predicted for potential lattice QCD calculations.
The generalized parton distributions (GPDs) for the spin-3=2 A+ resonance are studied numerically 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.
