Nucleon Electromagnetic and Axial Form Factors in a Light-front Constituent Quark Model
W. R. B. de Araújo, E. F. Suisso, J. P. B. C. de Melo +2
In the present work we study the effect of the scalar spin coupling of constituent quarks on the nucleon electroweak properties by introducing a valence light-front wave function w…

Faddeev Null Plane Model of Proton
W. R. B. de Araujo, J. P. B. C de Melo, T. Frederico
The proton is formulated as a relativistic system of three constituent quarks interacting via a zero-range two-body force in the null-plane. The covariance of the null-plane Faddee…
