Physics at a gamma gamma, e gamma and e-e- Option for a Linear Collider

Abstract

This report presents a review of the studies made in the working group on gamma gamma and e gamma physics" of the ECFA/DESY workshop on linear collider physics. It reports on several new physics studies, in particular s-channel Higgs production. A summary of R&D activities for the interaction region is presented. The merits of e-e- collisions are briefly recalled.
