Production of $Z$ Boson Pairs at Photon Linear Colliders

Abstract

The $ZZ$ pair production rate in high energy $\gamma \gamma$ collisions is evaluated with photons from laser backscattering. We find that searching for the Standard Model Higgs boson with a mass up to, or slightly larger than, 400 GeV via the $ZZ$ final state is possible via photon fusion with backscattered laser photons at a linear $e^{+}{e}^{-}$ collider with energies in the range 600 GeV $<\sqrt{s_{e^{+}{e}^{-}}}<$ 1000 GeV.
