EPP Theory Seminar: Ivan Schmidt: Low-scale seesaw from neutrino condensation

Abstract: An extension of the Standard Model for neutrino mass generation is proposed, with a low-scale seesaw mechanism via LNV condensation in the sector of sterile neutrinos. A simplified model of just one single family of elementary particles is analyzed, and checked it against a set of phenomenological constraints coming from electroweak symmetry breaking, neutrino masses, leptogenesis and dark matter. The model predicts (i) TeV scale quasi-degenerate heavy sterile neutrinos, suitable for leptogenesis with resonant enhancement of the CP asymmetry, (ii) a set of additional heavy Higgs bosons whose existence can be challenged at the LHC, (iii) an additional light and sterile Higgs scalar, which is a candidate for decaying warm dark matter, and (iv) a majoron. Since the model is based on simple and robust principles of dynamical mass generation, its parameters are very restricted, but remarkably it is still within current phenomenological limits.
