Radiative symmetry breaking at the Fermi scale and flat potential at the Planck scale

Radiative symmetry breaking at the Fermi scale and flat potential at the Planck scale

We investigate a possibility of the "flatland scenario," in which the electroweak gauge symmetry is radiatively broken via the Coleman-Weinberg mechanism starting from a completely flat Higgs potential at the Planck scale. We show that the flatland scenario is realizable only when an inequ...

Zusammenfassung:We investigate a possibility of the "flatland scenario," in which the electroweak gauge symmetry is radiatively broken via the Coleman-Weinberg mechanism starting from a completely flat Higgs potential at the Planck scale. We show that the flatland scenario is realizable only when an inequality K < 1 among the coefficients of the beta functions is satisfied. We show several models satisfying the condition.
