Abstract
In this work, a novel mechanism for spontaneous symmetry breaking is
presented. This mechanism allows to avoid quadratic divergencies and is
thus capable of addressing the hierarchy problem in gauge theories. Using
the scale-dependent effective action Γk minimally coupled to a gravitational
sector, variational parameter setting provides a mass and vacuum expectation value as a function of the constants arising in the low scale expansion
of Newtons’ and cosmological couplings. A comparison with experimental
data, such as the Higgs mass, allows putting restrictions on these constants.
This generic approach allows comparing with explicit candidates for an effective field theory of gravity. As an example, we use the asymptotic safety
scenario, where we find restrictions on the matter content of the theory.In this work, a novel mechanism for spontaneous symmetry breaking is
