Decays of a fermiophobic Higgs
  We explore the phenomenology of a fermiophobic Higgs: a Higgs whose couplings to fermions are suppressed. We calculate the branching ratios of a Higgs decaying to $\gamma\gamma$, $W^*W^*$, $Z^*Z^*$, $Zb\bar b$, $Z\gamma$, $\gamma b\bar b$, and final states involving vector mesons like $\Upsilon$, $J/\Psi$ and $\rho$. In order to calculate these branching ratios we perform a complete one-loop renormalization of the vertices $HZ\gamma$ and $H\gamma\gamma$. The decay mode $H\rightarrow \gamma\gamma$ is near unity for a Higgs below the $W$ mass, which provides a clean way of discovering a light fermiophobic Higgs. Interesting modes involving the vector mesons $Z$, $\gamma$, $\rho$, $J/\Psi$, and $\Upsilon$ are carefully analyzed.
