Search for Standard Model Higgs Boson via Vector Boson Fusion in the $H \to W^{+}W^{-} \to l^{\ pm} \nu jj$ with $120 \lt m_{H} \lt 250 GeV/c^ {2}$

The feasibility of discovering the Standard Model Higgs boson is investigated via Vector Boson Fusion in rm H to W^ + W^ - to rm ell nu jj channel. A comprehensive strategy of Higgs mass (rm m_H) reconstruction is developed using detector jets, lepton and missing transverse energy (rm E_T^miss). At an integrated luminosity of 30 rm fb^-1, a 5 rm sigma discovery can be achieved for rm 140 < m_H < 200 rm GeV/c^2. Several important techniques including forward jet tagging, central jet selection, hadronic and leptonic W reconstruction, rm E_T^miss selection, lepton-W correlation and lepton isolation, are optimized to increase the signal to background ratio. Data driven analysis methods are developed to further identify the experimental signature of the signal in addition to the reconstructed Higgs mass peak and reduce the effect of a variety of detector systematic uncertainties.
