Identifying the Higgs Boson in Electron--Photon Collisions

Abstract

We analyze the production and detection of the Higgs boson in the next generation of linear $e^{+}{e}^{-}$ colliders operating in the $e\gamma$ mode. In particular, we study the production mechanism $e+\gamma \to e\gamma \gamma \to e+H$, where one photon is generated via the laser backscattering mechanism, while the other is radiated via the usual bremsstrahlung process. We show that this is the most important mechanism for Higgs boson production in a $500$ GeV $e\gamma$ collider for $M_H\raisebox{-.4ex}{\rlap{$\sim$}} \raisebox{.4ex}{$>$}140$ GeV. We also study the signals and backgrounds for detection of the Higgs in the different decay channels, $b\bar{b}$, $W^{+}{W}^{-}$, and $ZZ$, and suggest kinematical cuts to improve the signature of an intermediate mass Higgs boson.
