Proposes testable predictions for future collider experiments.

Abstract

We propose a fundamental theory whose low-energy effective theory provides a phenomenological description of electroweak baryogenesis, radiative neutrino mass generation, and dark matter. The model is based on SUSY SU(2)_H gauge theory with confinement, and the model contains new Z_2 discrete symmetry and Z_2-odd right-handed neutrino superfields. The Higgs sector in the low energy effective theory of this model below confinement scale is described by fifteen mesonic superfields of fundamental SU(2)_H doublets. We present a benchmark scenario of this model, where all the constraints from the current neutrino, dark matter, lepton flavour violation and LHC data are satisfied. We also discuss how to test the scenario by the future collider experiments.
