Higgs finder and mass estimater

Abstract

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-1 luminosity. Without reconstruction of the events, we obtain estimators of the higgs mass from the peak and width of the signal distribution in (mll). 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 ET and the pT of leptons, are also prescribed. Our approach identifies the salient higgs to dilepton signatures that allow subtraction of the continuum W*W* background.
