Accepted: 3 January 2014
In the scalar-tensor model with Gauss-Bonnet and kinetic couplings, the power-law dark-energy solution may be described by a Higgs-type potential. It was found that in the solution describing the early time epoch of matter dominance, the potential presents a symmetry breaking phase, and the power-law solution leading to accelerated expansion corresponds to a Higgs-type potential in its symmetric shape.
