Searching for the intermediate-mass Higgs boson

We study the feasibility of detecting a neutral Higgs boson H⁰, with mass between 2mₜ{}80 GeV (by assumption) and 2mW at an e⁺{e}^{{{-}}}$ machine or the Superconducting Super Collider (SSC). Backgrounds to the production at an ${e}⁺e^- machine of H⁰ in association with a Z are calculated with particular emphasis on the case when mH{}mz. We present a detailed survey of the signals for and backgrounds to the inclusive or associated production at the SSC of H⁰ followed by the decay of H⁰ into one of the available channels. There is no signature which is established to be identifiable at the SSC. Only a few signatures remain to be studied, and the further calculations of most immediate interest are pointed out.
