內容摘要:  
Absract:
I will talk on a 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. I will 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.
