We present an analysis searching for Standard Model Higgs to WW* production in dilepton plus MET channels using 3.0 fb-1 of integrated luminosity. We find a total of 918 candidates with an expectation of 894.8 ± 113.2 background and 17.5 ± 2.2 signal for a Standard Model Higgs at 160 GeV/c2. In order to maximize sensitivity, the multivariate discriminants have been optimized separately for final states with either zero, one, or two or more identified jets. To gain extra acceptance, we also include associated production with a W or Z and vector boson fusion production mechanisms for events with one or more jets. The median expected 95% C.L. limit at a Higgs mass of 160 GeV/c2 is 1.7+0.7-0.5 times the Standard Model prediction, while the observed limit is 1.6 times the Standard Model prediction.
