High Energy Photon-Photon and Electron-Photon Collisions

Abstract

The advent of a next linear $e^{\pm }{e}^{-}$ 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 ${\gamma }^{\ast }{\gamma }^{\ast }\to X$ in the region dominated by BFKL hard Pomeron exchange and report the predicted cross sections at present and future $e^{\pm }{e}^{-}$ colliders. I also discuss exclusive $\gamma \gamma$ 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.
