Signature of the intermediate mass Higgs boson at the CERN LHC with flavor tagging

We examine the exclusive signature ${\mathit{e}}^{\pm }$(${\mathrm{\mu }}^{\pm }$)+bb¯ in the associated production of the intermediate mass Higgs boson with a W boson. We show that it is feasible to use this signature to identify the Higgs boson in the lower intermediate mass region (90 to 130 GeV) at the CERN LHC with reasonable acceptance cuts by assuming effective bottom-jet identification. We further demonstrate that the background can be reduced with judicious cuts down to the level of the signal.
