in weak boson fusion with dual forward jet tagging at the CERN LHC

Weak boson fusion promises to be a copious source of intermediate mass Standard Model Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the H → W W (∗) → eμ/pT decay mode for a Higgs boson mass in the 130-200 GeV range. A parton level analysis of the dominant backgrounds (production of W pairs, tt̄ and Z → ττ in association with jets) demonstrates that this channel allows the observation of H → W W (∗) in a virtually background-free environment, yielding a significant Higgs boson signal with an integrated luminosity of 5 fb or less. Weak boson fusion achieves a much better signal to background ratio than inclusive H → eμ/pT and is therefore the most promising search channel in the 130-200 GeV mass range.
