Ultra-weak sector, Higgs boson mass, and the dilaton
Abstract
The Higgs boson mass may arise from a portal coupling to a singlet field $$\sigma$$ which has a very large VEV $$f \gg m_\text{Higgs}$$. This requires a sector of "ultra-weak" couplings $$\zeta_i$$, where $$\zeta_i \lesssim m_\text{Higgs}^2 / f^2$$. Ultra-weak couplings are technically naturally small due to a custodial shift symmetry of $$\sigma$$ in the $$\zeta_i \rightarrow 0$$ limit. The singlet field $$\sigma$$ has properties similar to a pseudo-dilaton. We engineer explicit breaking of scale invariance in the ultra-weak sector via a Coleman-Weinberg potential, which requires hierarchies amongst the ultra-weak couplings.
