Valence quark contributions for the gamma N -> P11(1440) form factors
Valence quark contributions gamma N
2010/3/16
Using a covariant spectator quark model we estimate valence quark contributions to the F1*(Q2) and F2*(Q2) transition form factors for the gamma N -> P11(1440) reaction. The Roper resonance, P11(1440)...
