Nucleon Form Factors in the StrongCoupling Meson Theory
Abstract
Expressions for the electric form factors of the proton and neutron have been given in the chargedscalar and symmetrical pseudoscalar meson theories. Calculations have been done in the strongcoupling limit. Both theories explain the experimental data given by the Stanford and Cornell groups very well. In the pseudoscalar theory, however, we have to take an effective meson mass which is about onehalf of the rest mass. Small effective mass can be understood if a cubic term is introduced in the equation of motion for mesons. In the numerical integration of this equation, the strength g√λ has been obtained from the boundary conditions, g and λ being the coupling constants of the pionnucleon and pionpion fields, respectively. With numerical solutions, the nucleon form factors have been recalculated. They fit the experimental data quite well.
