The renormalization-group improved effective potential ---to leading-log and in the linear curvature approximation--- is constructed for ``finite'' theories in curved spacetime. It is not trivial and displays a quite interesting, exponential-like structure ---in contrast with the case of flat spacetime where it coincides with the classical potential. Several possible cosmological applications, as curvature-induced phase transitions and modifications of the values of the gravitational and cosmological constants, are briefly discussed.

  1. Two-Measure Electroweak Standard Model. Some aspects of cosmological evolution and vacuum stability

    hep-th 2025-01 reject novelty 5.0 of 10

    The paper derives a two-measure version of the electroweak Standard Model in which couplings run classically with the cosmological background, giving small-xi Higgs inflation and a reparameterized fermion mass hierarchy.
