We present a search for standard model Higgs boson to WW(*) production in dilepton plus missing transverse energy final states in data collected by the CDF II detector corresponding to 4.8/fb of integrated luminosity. To maximize sensitivity, the multivariate discriminants used to separate signal from background in the opposite-sign dilepton event sample are independently optimized for final states with zero, one, or two or more identified jets. All significant Higgs boson production modes (gluon fusion, associated production with either a W or Z boson, and vector boson fusion) are considered in determining potential signal contributions. We also incorporate a separate analysis of the same-sign dilepton event sample which potentially contains additional signal events originating from associated Higgs boson production mechanisms. Cross section limits relative to the combined SM predictions are presented for a range of Higgs boson mass hypotheses between 110 and 200 GeV/c^2.
