Abstract

We have performed the structural analysis of low-lying octet baryon members by assuming charge-isospin symmetry among quark flavors in transverse and longitudinal space. Using the light-cone spectator diquark model, we have investigated the electromagnetic form factors of the octet baryons and have compared them with the available data. Model scale has been estimated by comparing the valence $u$ quark's parton distribution function (PDF) of proton with the result of CTEQ5L parameterization. A comparative analysis of PDFs and generalized parton distributions (GPDs) for non-zero skewness among octet baryons has also been demonstrated. Fourier transform of the deeply virtual Compton scattering amplitude with respect to skewness has been further applied to study the diffraction patterns in the boost-invariant longitudinal position space.
