Elastic Scattering Processes in Scalar Electrodynamics at High Energies. I

Abstract
In this paper we study all elastic scattering amplitudes in scalar electrodynamics at high energies. The impact factors for the scalar meson and for the vector meson in this theory are explicitly calculated in the lowest order. We also show that the elastic amplitudes still satisfy an impact-factor representation after all vector-meson exchanges are summed, and an exponentiation, similar to that in quantum electrodynamics, is obtained.
