Abstract

In a class of supersymmetric gauge theories with asymptotic freedom, the low-energy effective theory below the confinement scale is described by the composite superfields of the fundamental representation fields. Based on the supersymmetric gauge theory with N_c=2 and N_f=3 with an additional unbroken Z₂ symmetry, we propose a new model where neutrino masses, dark matter, and baryon asymmetry of the Universe can be simultaneously explained by physics below the confinement scale. This is an example for the ultraviolet complete supersymmetric extension of so-called radiative seesaw scenarios with first-order phase transition required for successful electroweak baryogenesis. We show that there are benchmark points where all the neutrino data, the lepton flavor violation data, and the LHC data are satisfied. We also briefly discuss Higgs phenomenology in this model.
