Search for the standard model Higgs boson produced through vector boson fusion and decaying to b[bar over b]

A first search is reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair. Two data samples, corresponding to integrated luminosities of 19.8  fb[superscript −1] and 18.3  fb[superscript −1] of proton-proton collisions at √s = 8  T...

Description
Summary:A first search is reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair. Two data samples, corresponding to integrated luminosities of 19.8  fb[superscript −1] and 18.3  fb[superscript −1] of proton-proton collisions at √s = 8  TeV were selected for this channel at the CERN LHC. The observed significance in these data samples for a H → b[bar over b] signal at a mass of 125 GeV is 2.2 standard deviations, while the expected significance is 0.8 standard deviations. The fitted signal strength μ = σ/σ[subscript SM] = 2.8[+1.6 over −1.4]. The combination of this result with other CMS searches for the Higgs boson decaying to a b-quark pair yields a signal strength of 1.0 ± 0.4, corresponding to a signal significance of 2.6 standard deviations for a Higgs boson mass of 125 GeV.
