Four Weak Gauge Boson Production at Photon Linear Collider and Heavy Higgs Signal

Abstract

We study the signals and backgrounds 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 complete tree level SM calculation for these reactions. We show that the invariant mass spectrum of central $WW$, $ZZ$ pairs is sensitive to the signal from Higgs boson with a mass up to 1~TeV at a 2~TeV linear collider for integrated luminosity of 300~fb${}^{-1}$. At 1.5~TeV PLC Higgs boson with a mass up to 700~GeV can be studied. The nonresonant longitudinal gauge boson scattering ($m_H=\infty$) can be detected in photon-photon collisions at $e^{+}{e}^{-}$ center-of-mass energy of 3~TeV.
