Abstract

The dressed K-matrix model, developed previously for low- and intermediate-energy Compton scattering, is generalized to calculate the photon-nucleon vertex with a virtual photon and an off-shell nucleon. This model was used to compute the ratio of the proton electromagnetic form factors. The calculated ratio is in excellent agreement with the ratio measured in polarized electron-proton scattering.
