Abstract
We reconsider the signature of events with two charged leptons and missing energy as a signal for the detection of the standard model Higgs boson in the mass region =155–180 GeV. It is shown that a few simple experimental criteria allow us to distinguish events originating from the Higgs boson decaying to from the nonresonant production of at the CERN LHC. With this set of cuts, signal to background ratios of about one to one are obtained, allowing a 5–10 detection with about 5 of luminosity. This corresponds to less than one year of running at the initial lower luminosity . This is significantly better than for the hitherto considered Higgs boson detection mode , where in this mass range about 100 of integrated luminosity are required for a signal.
