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 sqrt (s) = 1.96 TeV p anti-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.
