Vector Boson Fusion leading to Higgs production and subsequent decay in bottom quarks

A search for the standard model Higgs boson in the vector boson fusion production channel with decay to bottom quarks is reported.

Sumario:A search for the standard model Higgs boson in the vector boson fusion production channel with decay to bottom quarks is reported. A data sample comprising 19.0 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 8 TeV collected during the 2012 running period has been analyzed and 95\% Confidence Level upper limits are derived for five masspoints from 115 to 135 GeV. At a Higgs boson mass of 125 GeV the observed limit is 3.6 while the expected limit is 3.0 times the standard model prediction. For a 125 GeV Higgs boson signal the fitted signal strength is $\mu$ = $\sigma/\sigma_{SM}$ = 0.7 $\pm$ 1.4.
