HIGGS OR NEUTRAL VECTOR BOSON PRODUCTION WITH A W-PAIR IN GAMMA-GAMMA-COLLISIONS

Exploiting the fact that W pair production in high-energy gammagamma collisions is very large, we use this process to trigger Higgs, Z or photon radiation. We find that there are sizeable rising cross-sections for triple bosons production. At energies about 1 TeV the new mechanism for Higgs production becomes very competitive with the dominant Higgs production processes in e+e- and egamma reactions. The effect of different polarized photon spectra obtained through back-scattered laser light on the electron beam of a linear collider is investigated. We give special attention to the search of the intermediate mass Higgs in WWH production and discuss how to effectively suppress the backgrounds.
