The Higgs boson offers a unique window to hidden sector fields S{sub i}, singlets under the standard model gauge group, via the renormalizable interactions |H|{sup 2}S{sub i}{sup 2}. 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.
