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.

• Cosmological backgrounds of gravitational waves and eLISA/NGO: phase transitions, cosmic strings and other sources (2012, methodology): “(16), is due to the total κ = κφ + κv, since both the gradient energy of the Higgs field and the kinetic energy of the bulk fluid motions lead to anisotropic stresses when the bubbles collide.”
