Search for a Fermiophobic Higgs Boson Decaying into Diphotons in pp̅ Collisions at sqrt[s]=1.96 TeV
A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb-1 of integrated luminosity from pp̅ collisions at sqrt[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 for one fermiophobic benchmark model.
