A search for a fermiophobic Higgs boson in the di-photon final states is reported based on CDF data from 7.0 fb^-1 of integrated luminosity. In contrast with the Standard Model, the coupling of the Higgs boson to fermions is suppressed in fermiophobic models. Therefore, the diphoton decay mode can be greatly enhanced. In the presented note, no evidence of a resonance in the diphoton 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. We found an observed (expected) limit on the Fermiophobic Higgs boson production excluding Higgs bosons particles with a mass m_hf < 114 GeV (m_hf < 111 GeV) at the 95% confidence level.
