The Minimal Supersymmetric extension of the Standard Model (MSSM) can pro-
vide the correct neutralino relic abundance and baryon number asymmetry of the
universe. Both may be efficiently generated in the presence of CP violating phases,
light charginos and neutralinos, and a light top squark. Due to the coannihilation of
the neutralino with the light stop, we find a large region of parameter space in which
the neutralino relic density is consistent with WMAP and SDSS data. We perform a
detailed study of the additional constraints induced when CP violating phases, consis-
tent with the ones required for baryogenesis, are included. We explore the possible tests
of this scenario from present and future electron Electric Dipole Moment (EDM) mea-
surements, direct neutralino detection experiments, collider searches and the b - sy
decay rate. We find that the EDM constraints are quite severe and that electron EDM
experiments, together with stop searches at the Tevatron and Higgs searches at the
LHC, will provide a definite test of our scenario of electroweak baryogenesis in the
next few years.
Here’s what’s next.
