The Higgs boson offers a unique window to hidden sectors via relevant (or marginal) operators. We prove that such interactions can provide new patterns for electroweak breaking (including radiative breaking by dimensional transmutation consistent with LEP bounds) and trigger the strong enough first order phase transition required by electroweak baryogenesis.
