Discovering a light Higgs boson with light

We evaluate the prospects for detecting a non-standard light Higgs boson with a significant branching ratio to two photons, in run II of the Fermilab Tevatron. We derive the reach for several channels: $2\gamma$ inclusive, $2\gamma +1\mathrm{}$ jet, and $2\gamma +2\mathrm{}$ jets. We present the expected run II limits on the branching ratio of $\overrightarrow{h}\gamma \gamma$ as a function of the Higgs boson mass, for the case of “bosonic,” as well as “top-color” Higgs bosons.
