Abstract:

We present an update of the CDF search for a Standard Model Higgs boson decaying into a pair of W bosons using the eτ and μτ signatures. Using 7.1 fb-1 of data collected with the high-pT electron and muon triggers, we reconstruct and select all candidate events with either an electron or a muon and a hadronic tau in the final state.
We expect 504 ± 02 background events in the eτ channel and 325 ± 50 events in the μτ channel and 1.04 ± 0.12 and 0.63 ± 0.07 signal events, respectively, for a Higgs mass of 160 GeV/c2. In data we observe 507 eτ events and 333 μτ events. We set a 95% C.L. upper limit on σ/σSM of 23.1 for a Higgs mass hypothesis of 160 GeV/c2. The expected 95% C.L. upper limit for the same mass is 15.1.
