A search for a narrow Higgs boson resonance in the diphoton mass spectrum is presented based on data corresponding to 7.0 fb−1 of integrated luminosity from p{bar p} collisions at √s = 1.96 TeV collected by the CDF experiment. No evidence of such a resonance is observed, and upper limits are set on the cross section times branching ratio of the resonant state as a function of Higgs boson mass. The limits are interpreted in the context of the standard model and one fermiophobic benchmark model where the data exclude fermiophobic Higgs bosons with masses below 114 GeV/c2 at a 95% Bayesian credibility level.

We present a search for the Standard Model Higgs boson decaying into a pair of photons produced in p$p\bar{p}$ collisions with a center of mass energy of 1.96 TeV. The results are based on data corresponding to an integrated luminosity of 10 fb-1 collected by the CDF II detector. Higgs boson candidate events are identified by reconstructing two photons in either the central or plug regions of the detector. The acceptance for identifying photons is significantly increased by using a new algorithm designed to reconstruct photons in the central region that have converted to an electron-positron pair. In addition, a new neural network discriminant is employed to improve the identification of non-converting central photons. No evidence for the Higgs boson is observed in the data, and we set an upper limit on the cross section for Higgs boson production multiplied by the H 2![gamma][gamma] branching ratio. For a Higgs boson mass of 125 GeV/c 2, we obtain an observed (expected) limit of 12.2 (10.8) times the Standard Model prediction at the 95% credibility level.

A search for the standard model Higgs boson is presented using events with two charged leptons and large missing transverse energy selected from 5.4 fb−1 of integrated luminosity in p{bar p} collisions at √s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. No significant excess of events above background predictions is found, and observed (expected) upper limits at 95% confidence level on the rate of Higgs boson production are derived that are a factor of 1.55 (1.36) above the predicted standard model cross section at m{sub H} = 165 GeV.

A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb−1 of integrated luminosity from p{bar p} collisions at √s = 1.96 TeV collected by the CDF experiment. No evidence of a resonance in the diphoton mass spectrum is observed, and upper limits are set on the cross section times branching fraction of the resonant state as a function of Higgs boson mass. The resulting limits exclude Higgs bosons with masses below 106 GeV/c2 at a 95% Bayesian credibility level (C.L.) for one fermiophobic benchmark model.

In this Thesis the electro-weak spontaneous symmetry breaking of the Standard Model (SM) is studied by searching for the scalar Higgs particle in the proton antiproton collisions of the Tevatron collider, at the center of mass energy √s = 1.96 TeV. We report on the inclusive search for the Higgs boson decaying to two W bosons in the final state characterized by two charged leptons (e or [mu]) and two neutrinos. The analysis of 4.8 fb$^{-1}$ of data recorded by the Collider Detector at Fermilab (CDF) shows no evidence of its production. We set 95% Confidence Level upper limits on the production cross section as a function of the mass $m_H$ in the range 110 to 200 GeV/$c^2$. For $m_H$ = 165 GeV/$c^2$ the observed limit is 1.3 times the SM predicted cross section ([sigma]H); the expected limit, in absence of signal, is 1.2+0.6 -0.4[sigma](H). These limits are the most stringent ones set by a single experiment up to date, for $m_H$ > 130 GeV/c2.
