Search for the intermediate Mass Higgs Signal at TeV $e\gamma$ colliders

Abstract

The intermediate mass Higgs (IMH) can be abundantly produced through the process $e^{-}\gamma \to W^{-}H\nu$ at TeV $e^{-}\gamma$ colliders, which are realized by the laser back-scattering method. We search for the signature of $W^{-}H\to (jj)(b\bar{b})$ plus missing transverse momentum, with and without considering the $b$-tagging. We also analyse all the potential backgrounds from $e^{-}\gamma \to W^{-}Z\nu ,W^{-}{W}^{+}{e}^{-},ZZ{e}^{-},\bar{t}b\nu$ and $t\bar{t}{e}^{-}$. 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 discovery should be viable. We also present detail formulas for the helicity amplitudes of these processes.
