Abstract

We present an analysis searching for Standard Model Higgs to WW* production in dilepton plus MET channels using 2.4 fb-1 of integrated luminosity. We find 661 candidates with an expectation of 626 +- 54 background and 9.5 signal for Standard Model Higgs at 160 GeV/c2. In order to maximize sensitivity, a combined Matrix Element method and neural network approach is utilized to distinguish signal from background processes. The median expected 95% C.L. limit at a Higgs mass of 160 GeV/c2 is 2.5+1.0-0.7 times the Standard Model prediction at NNLL, while the observed limit is 1.6 times the Standard Model prediction.
