{\Large{\bf Higgs or Neutral Vector Boson Production with a $W$ Pair in {\LARGE $γγ$} Collisions}}

Abstract

Exploiting the fact that $W$ pair production in high-energy $γγ$ 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 $1TeV$ the new mechanism for Higgs production becomes very competitive with the dominant Higgs production processes in $e^+e^-$ and $e γ$ 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 a special attention to the search of the intermediate mass Higgs in $WWH$ production and discuss how to effectively suppress the backgrounds.
