We study the impact of recent direct and indirect searches for particle dark
matter on supersymmetric models with resonant neutralino- or chargino-driven
electroweak baryogenesis (EWB) and heavy sfermions. We outline regions of
successful EWB on the planes defined by gaugino and higgsino mass parameters,
and calculate the portions of those planes excluded by dark matter search
results, and the regions soon to be probed by current and future experiments.
We conclude that dark matter searches robustly exclude a wino-like lightest
supersymmetric particle in successful EWB regions. Bino-like dark matter is
still a possibility, although one that will be probed with a modest improvement
in the sensitivity of current direct and indirect detection experiments. We
also calculate the total production cross section of chargino and neutralino
pairs at the Large Hadron Collider, with a center of mass energy of 7 and 14
TeV.
