Invisible dilaton

Brax, Philippe; Valageas, Patrick; Burrage, Clare +1 more

We analyze the dynamics of a light scalar field responsible for the µ term of the Higgs potential and coupled to matter via the Higgs-portal mechanism. We find that this dilaton model is stable under radiative corrections induced by the standard model particle masses. When the background value of the scalar field is stabilized at the minimum…
