A search for the Higgs boson in the diphoton decay channel is reported. Although the Standard Model branching fraction is small, the diphoton final state is appealing due to better diphoton mass resolution compared with dijet final states. In addition, other models - such as fermiophobic models where the Higgs does not couple to fermions - predict much larger branching fractions for the diphoton decay. Here, for the first time, we search diphoton data from the CDF experiment for signs of a standard model Higgs boson.

Public note for Winter '10 conferences.

The results should be considered preliminary until published in a refereed journal. They can be used in conference presentations with proper reference to the CDF Collaboration.
