High Energy Photon-Photon and Electron-Photon Collisions
Abstract
The advent of a next linear e e- collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ* γ* X in the region dominated by BFKL hard Pomeron exchange and report the predicted cross sections at present and future e e- colliders. I also discuss exclusive γ γ reactions in QCD as a measure of hadron distribution amplitudes and a new method for measuring the anomalous magnetic and quadrupole moments of the W and Z gauge bosons to high precision in polarized electron-photon collisions.
