Implications

• Strong 1st order EWPT w/o light stop
• New sources of CPV relaxation
• Light singlet Higgs
• Singlino CDM.

Conclusions

• Explaining the origin of matter remains an
  important task at the interface of particle
  physics, nuclear (hadronic) physics, and
  cosmology
• CP-violation beyond that of the SM is needed to
  provide such an explanation
• Recent theoretical developments in baryogenesis
  are putting baryon asymmetry computations on
  firmer ground
• New EDM and dark matter searches -- together
  with precision electroweak and collider studies
  (especially the ILC) -- will provide
  complementary and essential tests of matter
  production at the electroweak scale
