The minimal standard model, viewed as an effective theory with spontaneously broken scale invariance, predicts light, feebly coupled dilaton. Although, the microscopic physics is almost indistinguishable from the standard model, the cosmological evolution is entirely different due to the presence of nearly flat direction in the Higgs-dilaton potential. Most notably, the electroweak phase transition is necessarily driven by the QCD chiral symmetry breaking phase transition, and thus occurs at ~100 MeV. This opens a novel scenario for the electroweak baryogenesis, which I will describe in this talk.
