摘要：

We examine the prospects for extending the Tevatron reach for a Standard Model Higgs boson by including the semileptonic Higgs boson decays h → WW → ℓνℓjj for Mh ≳ 2 MW, and h → Wjj → ℓνℓjj for Mh ≲ 2 MW, where j is a hadronic jet. We employ a realistic simulation of the signal and backgrounds using the Sherpa Monte Carlo event generator. We find kinematic selections that enhance the signal over the dominant W+ jets background. The resulting sensitivity could be an important addition to ongoing searches, especially in the mass range 120 ≲ Mh ≲ 150 GeV. The techniques described can be extended to Higgs boson searches at the Large Hadron Collider.
