Finding the Leptonic $WW$ Decay Mode of a Heavy Higgs Boson

Abstract

We reanalyze the extraction of the heavy Higgs boson signal $H\to W^{+}{W}^{-}\to \bar{\ell }\nu ,\ell \bar{\nu }$ $(\ell =eor\mu )$ from the Standard Model background at hadron supercolliders, taking into account revised estimates of the top quark background. With new acceptance criteria the detection of the signal remains viable. Requiring a forward jet-tag, a central jet-veto, and a large relative transverse momentum of the two charged leptons yields $S/\sqrt{B}>6$ for one year of running at the SSC or LHC.
