Observing high mass Higgs using pp to qqH at CERN CMS experiment

The observability of the Higgs signal in the mass range of 300-800 Ge V is searched in the vector boson fusion process with the CMS experiment. at LHC. The fusion process is characterized by two final state jets at large pseudorapidity. The forward calorimeter plays a key role in detecting these jets. The significant signals are obtained for H to WW to l nu jj and H to ZZ to lljj. Importance of the forward jet tagging is emphasized to extract the signal from the large QCD W/Z +jets and the tt backgrounds. This analysis shows that the Higgs with m/sub H/ = 300-800 GeV can be observed in WW and ZZ decay channels with an integrated luminosity of about 10 to 20 fb/sup -1/. (5 refs).
