Stable mass hierarchies and dark matter from hidden sectors in the scale-invariant standard model
Stable mass hierarchies and dark matter from hidden sectors in the scale-invariant standard model
Scale invariance may be a classical symmetry which is broken radiatively. This provides a simple way to stabilise the scale of electroweak symmetry breaking against radiative corrections. But for such a theory to be fully realistic, it must actually incorporate a hierarchy of scales, including the Planck and the neutrino …
