A Model of Fermion Flavor and Leptogenesis and Cold Dark Matter

TL;DR

This paper proposes a new particle physics model that unifies fermion flavor, leptogenesis, and dark matter at the TeV scale, fitting current data and predicting testable new phenomena.

Contribution

It introduces a novel model with a local $U(1)_{B-L}$ gauge symmetry and SO(3) flavor symmetry, including a fourth fermion generation with dark matter candidate.

Findings

Successfully fits all current experimental data.

Predicts new testable phenomena in future experiments.

Provides a unified framework for fermion masses, flavor mixing, baryon asymmetry, and dark matter.

Abstract

I suggest a new particle model to integrate the fermion flavor, the TeV scale Leptogenesis and cold dark matter. The model has a local gauge symmetry $U(1)_{B-L}$ at the TeV scale and a flavor family symmetry SO(3), in addition, it also contains the fourth generation fermions in which including a cold dark matter neutrino. The model can simultaneously account for the fermion masses and flavor mixings, and the baryon asymmetry and cold dark matter. It not only excellently fits all the current experimental data, but also predicts some new results which are promising to be test in future experiments.
