Title:

UV complete model for Electroweak Baryogenesis, Radiative neutrino mass and Dark Matter

Abstract:

We want to construct a UV complete theory whose low-energy effective theory
provides a phenomenological description of strongly first order electroweak phase
transition necessary for the electroweak baryogenesis, radiative neutrino mass generation,
and dark matter (such as the Aoki-Kanemura-Seto model and the Ma-model).
Our fundamental model is based on SUSY SU(2)_H gauge theory with confinement.
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.
