Abstract
A strong-coupling approximation method for the Chew-Low meson-nucleon scattering formalism is developed, considering, for simplicity, the case of charged scalar mesons. As a starting point, the Low equation formulated for the case of strong coupling is stated. This formulation explicitly takes into account the formation of excited compound-nucleon states which arise in the case of strong coupling. The data concerning the zero-meson part and the compound-nucleon excitation energies, necessary to specify this Low equation, are introduced approcimatly by means of the field-splitting transformation developed in a previous paper. The one-meson approximation is constructed; this corresponds to a certain kind of many-meson approximation of the usual Low equation whose limit asg→∞ holds exactly. It is hoped that these considerations will serve to guide an analogous investigation using the pseudoscalar theory.
