Gravitational form factors and angular momentum densities in light-front quark-diquark model

Understand

We investigate the gravitational form factors (GFFs) and the longitudinal momentum densities ($p^+$ densities) for proton in a light-front quark-diquark model.

• The light-front wave functions are constructed from the soft-wall AdS/QCD prediction.
• The contributions from both the scalar and the axial vector diquarks are considered here.
• The results are compared with the consequences of a parametrization of nucleon generalized parton distributions (GPDs) in the light of recent MRST measurements of parton distribution functions (PDFs) and a soft-wall AdS/QCD model.
