  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
Z_2 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.
