Abstract

This thesis deals with the physics of two photon processes. We first introduce covariant perturbation theory and apply it to some quantum electrodynamics processes. We start with study of electron-positron pair production in the field of a static nucleus. We then deal with applications to electron-positron pair production through collision of virtual photons in high energy electron-electron scattering. Next we study the pair conversion of bremsstrahlung photon in high energy proton-proton scattering. Detailed evaluations of cross sections are given
