gamma-gamma Interactions from Real to Virtual Photons

Abstract

A `complete' framework for gamma-gamma / gamma*-gamma / gamma*-gamma* interactions is presented. The emphasis is on providing a model for gamma-gamma physics at all photon virtualities, including the difficult transition region around the rho meson mass.
