Searches for the Higgs boson decaying to W+W -?l+?l-?¯ with the CDF II detector

Abstract: We present a search for a standard model Higgs boson decaying to two W bosons that decay to leptons using the full data set collected with the CDF II detector in ?s=1.96??TeV p¯p collisions at the Fermilab Tevatron, corresponding to an integrated luminosity of 9.7??fb?1. We obtain no evidence for production of a standard model Higgs boson with mass between 110 and 200??GeV/c2, and place upper limits on the production cross section within this range. We exclude standard model Higgs boson production at the 95% confidence level in the mass range between 149 and 172??GeV/c2, while expecting to exclude, in the absence of signal, the range between 155 and 175??GeV/c2. We also interpret the search in terms of standard model Higgs boson production in the presence of a fourth generation of fermions and within the context of a fermiophobic Higgs boson model. For the specific case of a standard-model-like Higgs boson in the presence of fourth-generation fermions, we exclude at the 95% confidence level Higgs boson production in the mass range between 124 and 200??GeV/c2, while expecting to exclude, in the absence of signal, the range between 124 and 221??GeV/c2.
