Abstract
We present a combination of searches for the standard model Higgs boson using the full CDF run II data set, which corresponds to an integrated luminosity of collected from collisions at the Fermilab Tevatron. The searches consider Higgs boson production from gluon-gluon fusion, vector-boson fusion, and associated production with either a or boson or a pair. Depending on the production mode, Higgs boson decays to , , , , and are examined. We search for a Higgs boson with masses () in the range . In the absence of a signal, we expect based on combined search sensitivity to exclude at the 95% credibility level the mass regions , , and . The observed exclusion regions are and . A moderate excess of signal-like events relative to the background expectation at the level of 2.0 standard deviations is present in the data for the search hypothesis. We also present interpretations of the data within the context of a fermiophobic model and an alternative standard model incorporating a fourth generation of fermions. Finally, for the hypothesis of a new particle with mass , we constrain the coupling strengths of the new particle to bosons, bosons, and fermions.
