A UV complete model for radiative seesaw and electroweak baryogenesis based on the SUSY gauge theory

TL;DR

This paper presents a UV-complete supersymmetric gauge theory model that simultaneously explains neutrino masses, dark matter, and baryon asymmetry through radiative seesaw mechanisms and electroweak baryogenesis, consistent with current experimental data.

Contribution

It introduces a novel supersymmetric gauge theory framework with N_c=2, N_f=3, and Z_2 symmetry that unifies explanations for neutrino masses, dark matter, and baryogenesis at low energies.

Findings

Model satisfies neutrino oscillation data

Consistent with lepton flavor violation constraints

Aligns with LHC and Higgs phenomenology observations

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 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.
