Fermiophobic and other non-minimal neutral Higgs bosons at the LHC

Abstract

The phenomenology of neutral Higgs bosons from non--SUSY, extended Higgs sectors is studied in the context of the LHC, with particular attention given to the case of a fermiophobic Higgs. It is found that enhanced branching ratios to $\gamma \gamma$ and ${\tau }^{+}{\tau }^{-}$ are possible and can provide clear signatures, while detection of a fermiophobic Higgs will be problematic beyond a mass of 130 GeV.
