Standard Model CP and Baryon Number Violation in Cold Electroweak   Cosmology
  Contrary to popular beliefs, it is possible to explain Baryonic asymmetry of the Universe inside the Standard Model, provided inflation ended into a broken phase below the electroweak transition. Two important ingredients of the solution are multiquanta "Higgs bags", containing W,Z and top quarks, as well as sphaleron transitions happening inside these bags. Together, they provide baryon number violation at the level $10^{-2..3}$. Our recent calculations show that CP violation (due to the usual CKM matrix of quark masses in the 4-th order) leads to top-antitop population difference in these bags of about $10^{-9}$. (The numbers mentioned are not yet optimized and simply follow a choice made by some numerical simulations of the bosonic fields we used as a reference point.)
