Search for the intermediate mass Higgs signal at TeVeγcolliders

The intermediate mass Higgs boson can be abundantly produced through the process $e^{-}\gamma \to W^{-}H\nu$ at TeV $e^{-}\gamma$ colliders, which are realized by the laser backscattering method. We search for the signature of $W^{-}H\to \mathrm{}\left(\mathrm{jj}\right)\left(b\overline{b}\right)$ plus missing transverse momentum, with and without considering $b$ tagging. We also analyze all the potential backgrounds from $e^{-}\gamma \to W^{-}Z\nu$, $W^{-}{W}^{+}{e}^{-}$, $\mathrm{ZZ}{e}^{-}$, $\overline{t}b\nu$, and $t\overline{t}{e}^{-}$. With our selective acceptance cuts these backgrounds are reduced to a manageable level. We find that for the entire intermediate mass range 60 - 150 GeV the Higgs boson discovery should be viable. We also present detailed formulas for the helicity amplitudes of these processes.
