| contents | We discuss the possibility that dark energy arises from a strongly-coupled Higgs-Yang-Mills set of interacting fields in the non-perturbative regime. We choose the simplest $SU(2)$ representation, which is compatible with the Cosmological Principle. One of the components of the Higgs doublet act as an effective quintessence scalar field interacting with both gravity and the gauge field. We devise a multiple time scale approach to solve the equations of motion through a hierarchy of the couplings, utilizing exact solutions in terms of Jacobi elliptic functions. We observe that the time scale of variation of the Hubble constant is the slowest one, while, for the scalar field, assuming that its self-coupling is smaller than the coupling of the gauge field, represents an intermediate time scale. From the consistency of the Friedmann equations, we show how the effect of the scalar field is to give origin to dark energy with a proper equation of state corrected by a very small time-dependent term. Finally, agreement with cosmological data for the dark energy density is shown without relying on the fine-tuning of the physical constants of the model. |
