Accelerated expansion of the Universe and the Higgs true vacuum
Abstract
Scalar fields which are favorite among the possible candidates for the dark energy usually have degenerate minima at φmin. In the presented work, we discuss a two Higgs doublet model with the non-degenerate vacuum named inert uplifted double well type two-Higgs doublet model (UDW-2HDM) for the dark energy. It is shown that when the both Higgs doublets lie in their respective true minima then one Higgs doublet can cause the current accelerated expansion of the Universe.
