Search for a light fermiophobic Higgs boson produced via gluon fusion at Hadron Colliders

In this study, we propose new Higgs production mechanisms with multi-photon final states in the fermiophobic limit of the Two Higgs Doublet Model. The processes are: gg -> hh, gg -> H h followed by H -> h h and gg -> A h followed by A -> h Z. In the fermiophobic limit, gg -> h h and gg -> A h -> h h Z would give rise to 4 photon signature while gg -> H h -> h h h can give a 6 photon final state. We show that both the Fermilab Tevatron and CERN's Large Hadron Collider can probe a substantial slice of the parameter space in this fermiophobic scenario of the Two Higgs Doublet Model. If observed the above processes can give some information on the triple Higgs couplings involved.
