Higgs boson finder and mass estimator: The Higgs boson to WW to leptons decay channel at the LHC
- Department of Physics, University of Wisconsin, Madison, Wisconsin 53706 (United States)
We exploit the spin and kinematic correlations in the decay of a scalar boson into a pair of real or virtual W-bosons, with both W-bosons decaying leptonically, for Higgs boson discovery at 7 TeV LHC energy with 10 fb{sup -1} luminosity. Without reconstruction of the events, we obtain estimators of the Higgs mass from the peak and width of the signal distribution in m{sub ll}. The separation of signal and background with other distributions, such as the azimuthal angle between two W decay planes, the rapidity difference between the two leptons, missing E{sub T}, and the p{sub T} of leptons, are also prescribed. Our approach identifies the salient Higgs to dilepton signatures that allow subtraction of the continuum W*W* background.
