Four Weak Boson Production in Tev Photon--Photon Collisions and Heavy Higgs Signal

Abstract

We study the signals for a heavy Higgs boson in the processes $\gamma \gamma \to WWWW$, $\gamma \gamma \to WWZZ$ at the photon linear collider. The results are based on the first complete tree level calculation for these reactions. Using a forward ``spectator" $W$ tag, central ``spectator" $W$ veto to suppress backgrounds from transverse $W$, $Z$ production we show that the invariant mass spectrum of central $WW$, $ZZ$ pairs is sensitive to Higgs boson with a mass up to 1~TeV at a 2~TeV linear collider.
