Detecting a light Higgs boson at the Fermilab Tevatron through enhanced decays to photon pairs - art. no. 015006

We analyze the prospects of the Fermilab Tevatron for finding a Higgs boson in the two photon decay mode. We conclude that the standard model (SM) Hig gs boson will likely not he discovered in this mode. However, we motivate s everal theories beyond the SM, including the MSSM, which predict a Higgs bo son with enhanced branching fractions into photons, and calculate the lumin osity needed to discover a general Higgs boson at the Tevatron by a two-pho ton invariant mass peak at large transverse momentum. We find that a high l uminosity Tevatron will play a significant role in proving or constraining these theories.
