The Higgs boson offers a unique window to hidden sector fields Si, singlets under the standard model gauge group, via the renormalizable interactions |H|2Si2. We prove that such interactions can provide new patterns for electroweak breaking, including radiative breaking by dimensional transmutation consistent with CERN LEP bounds, and trigger the strong enough first-order phase transition required by electroweak baryogenesis. © 2007 The American Physical Society.
