In the scalar-tensor model with Gauss-Bonnet and kinetic couplings, the
power-law dark energy solution may be described by Higgs-type potential. It was
found that in the solution describing early time epoch of matter dominance, the
potential presents symmetry breaking phase, and the power law solution leading
to accelerated expansion corresponds to Higgs-type potential in its symmetric
shape.Comment: 16 pages, 1 figure; accepted in EP
