Investigations in hadron physics: Bound state models for fermons; radiative corrections to pionpion scattering
Abstract
Trajectories of fermion Regge poles are calculated in a model in which a spin 1/2 particle is bound to a spin 0 core. The BetheSalpeter equation in the ladder approximation provides a relativistic description of the model in which a fundamental interaction is unitarized. Results are obtained numerically from a covariant separable approximation to the kernel of the partialwave integral equation. Two kinds of interactions are considered: the single particle exchange kernel and an exponentially damped kernel. A chiral SU(2)XSU(2) Lagrangian is used to describe lowenergy pionpion scattering. Radiative corrections are calculated by modifying in a guage invariant way the strong interaction Lagrangian in the presence of the electromagnetic field. Corrections to the cross section are calculated to 0 (alpha).
