Search for $h_f\to \gamma \gamma$ with the D0 detector at $\sqrt{s}=1.96$ TeV

Abstract

We report the results of a search for a narrow resonance decaying into two photons in 1.1 fb${}^{-1}$ of data collected by the D0 experiment at the Fermilab Tevatron Collider during the period 2002-2006. We find no evidence for such a resonance and set a lower limit on the mass of a fermiophobic Higgs boson of $m_{h_f}>100$ GeV at the 95% C.L. This exclusion limit exceeds those obtained in previous searches at the Tevatron and covers a significant region of the parameter space $B(h_f\to \gamma \gamma )$ vs. $m_{h_f}$ which was not accessible at the CERN LEP Collider.
