Neural Network Based Search for Higgs Boson Produced via VBF with $H \rightarrow W^+W^- \rightarrow l^+ l^- \sla{p_{T}}$ for $115<M_H<130~\gev$
The sensitivity to a low mass Higgs produced via Vector Boson Fusion is investigated. The complicated signature of $H \rightarrow W^+W^- \rightarrow l^+l^-\sla{p_{T}}$ motivates the use of multivariate analysis techniques. A neural network has been trained to discriminate between signal and backgrou...

| description | The sensitivity to a low mass Higgs produced via Vector Boson Fusion is investigated. The complicated signature of $H \rightarrow W^+W^- \rightarrow l^+l^-\sla{p_{T}}$ motivates the use of multivariate analysis techniques. A neural network has been trained to discriminate between signal and background in the Higgs mass range $115<M_H<130~\gev$. The improvement of the significance from the cut-based analysis ranges from 20-35\%. By including likelihood ratio techniques in the sensitivity calculation, an additional 15\% improvement is obtained. |
