On the Cosmological Origin of the Homogeneous Scalar Field in Unified Theories

Abstract

We consider the possibility of describing the Higgs effect in unified theories without the Higgs potential in the presence of the Einstein gravity with the conformal gravity-scalar coupling under the assumption of homogeneous matter distribution. The scalar field values can be found from the Friedmann equations for the homogeneous Universe. The considered cosmological mechanism solves the vacuum density problem (we got $\rho_\phi^{Cosmic}=10^{-34}\rho_{cr}$ instead of $\rho_\phi^{Higgs}=10^{54}\rho_{cr}$),and exludes the monopole creation and the domain walls.
