Abstract Under a hypothesis of classically conformal theories, we investigate the minimal B – L extended Standard Model, which naturally provides the seesaw mechanism for explaining tiny neutrino masses. In this setup, the radiative gauge symmetry breaking is successfully realized in a very simple way: The B – L gauge symmetry is broken through the conformal anomaly induced by quantum corrections in the Coleman–Weinberg potential. Associated with this B – L symmetry breaking, the Higgs mass parameter is dynamically generated, by which the electroweak symmetry breaking is triggered. We find that a wide range of parameter space can satisfy both the theoretical and experimental requirements.
