The superweak force is a minimal, anomaly-free U(1) extension of the standard model, designed to explain the origin of (i) neutrino masses and mixing matrix elements, (ii) dark matter, (iii) cosmic inflation, (iv) stabilization of the electroweak vacuum and (v) leptogenesis. In this talk we discuss the phenomenological status of the model and  provide viable scenarios for the physics of the items in this list.

The talk is based on the following research articles on the arXiv: 1812.11189 (Symmetry), 1911.07082 (PRD), 2104.11248 (JCAP), 2104.14571 (PRD), 2105.13360 (J.Phys.G), 2204.07100 (PRD), 2301.07961 (JHEP), 2301.06621 (PRD), 2305.11931 (PRDL) and correspondence with the Budapest-Marseille-Wuppertal group, written in collaboration with S.
