Proceedings of the first meeting on eγ/γγ colliders

The first meeting on eγ/γγ colliders was held on September 28 and 29, 1993, at the National Laboratory for High Energy Physics. After general remarks were delivered, lectures were given on QED in intense laser field, photon linear collider, laser focusing, luminosity distribution in the eγ/γγ colliders, QCD correction for γγ→H, radiation correction for eγ/νW process, SUSY particle production at the eγ and γγ colliders, formation of e* in eγ collision, and general remarks on the theory. Discussion was carried out on 'Where are we going from here?' In this book, the gists of the lectures are collected. (K.I.)
