Review of Two Photon Physics

摘要

This talk is intended as an introduction for those not yet expert in two-photon physics, especially those e exp + e exp - one-photon physicists who still think of two-photon events as background. I concentrate on the physics questions involved, especially emphasizing the areas where I feel progress can be made in the near future, and of necessity leaving most experimental details to be found in the references. After a quick survey of the field and a few words about kinematics, I discuss in detail two major fields: the photon structure function and resonance production. (ERA citation 08:042600)
