Valence quark contributions for the form factors

G Ramalho, K Tsushima - Physical Review D—Particles, Fields, Gravitation …, 2010 - APS
Using a covariant spectator quark model we estimate valence quark contributions to the F
1*(Q 2) and F 2*(Q 2) transition form factors for the γ N→ P 11 (1440) reaction. The Roper …
