Axial vector form factor of nucleons in a light-cone diquark model
Bo-Qiang Ma, Di Qing, Ivan Schmidt
The nucleon axial vector form factor is investigated in a light-cone quark spectator diquark model, in which Melosh rotations are applied to both the quark and vector diquark. It i…

Electromagnetic Form Factors of Nucleons in a Light-cone Diquark Model
Bo-Qiang Ma, Di Qing, Ivan Schmidt
We investigate the electromagnetic form factors of nucleons within a simple relativistic quark spectator-diquark model using the light-cone formalism. Melosh rotations are applied…

Photo-production of Nucleon Resonances and Nucleon Spin Structure Function in the Resonance Region
Di Qing, Ivan Schmidt
The photo-production of nucleon resonances is calculated based on a chiral constituent quark model including both relativistic corrections H{rel} and two-body exchange currents, an…
