Abstract

Higgs boson production with subsequent decay to photons was searched for in the data collected by the DELPHI detector at centre-of-mass energies between 183 GeV and 209 GeV, corresponding to a total integrated luminosity of nearly 650 pb^-1. No evidence for a signal was found, and limits were set on h ⁰ Z ⁰ and h ⁰ A ⁰ production with h ⁰ decay to photons. These results were used to exclude regions in the parameter space of fermiophobic scenarios of Two Higgs Doublet Models.
