Abstract
Fermiophobic Higgs bosons (hf) exhibiting large branching ratios for decay to two photons can arise in models with two or more scalar doublets and/or triplets. In such models the conventional production mechanisms at hadron colliders, which rely on the hfVV coupling (V=W,Z), may be rendered ineffective due to severe mixing angle suppression. In this scenario, double hf production may proceed via the complementary mechanism qq’→H±hf with subsequent decay H±→hfW*, leading to events with up to four photons. We perform a simulation of the detection prospects of hf in the multi-photon (>3) channel at the Fermilab Tevatron and show that a sizeable region of the (mH±,mhf) parameter space can be probed during Run II.
