Title: Higgs Boson Signatures of MSSM Electroweak Baryogenesis

Abstract

Electroweak baryogenesis in the MSSM can account for the cosmological baryon asymmetry, but only with a very light scalar top and a SM-like Higgs boson. We investigate the effects of this light scalar top on Higgs boson production and decay. Relative to the standard model Higgs boson, we find a large enhancement of the Higgs production rate through gluon fusion and a suppression of the Higgs branching fraction into photon pairs. These modifications in the properties of the Higgs boson are large enough that they can potentially be tested at the Tevatron and the LHC.
