Searching for a light Fermiophobic Higgs Boson at the Tevatron

Abstract

We propose new production mechanisms for light fermiophobic Higgs bosons ($h_f$) with suppressed couplings to vector bosons ($V$) at the Fermilab Tevatron. These mechanisms (e.g. $q{q}^{\prime }\to H^{\pm }{h}_f$) are complementary to the conventional process $q{q}^{\prime }\to V{h}_f$, which suffers from a strong suppression of $1/{\tan }^2\beta$ in realistic models with a $h_f$. The new mechanisms extend the coverage at the Tevatron Run II to the larger $\tan \beta$ region, and offer the possibility of observing new event topologies with up to 4 photons.
