Abstract

A brief summary of the CMS discovery potential for the Standard Model Higgs boson in the H->gamma+gamma channel is presented. We review both a standard cut-based search and a more optimized analysis that takes advantage of the wide range of signal/background expectations as function of the possible selection cuts. As the Higgs discovery in this channel will rely heavily on performance of the CMS electromagnetic calorimeter, the relevant aspects of its design and operation in situ at the LHC are also briefly discussed.
