# A Model of Dark Matter, Leptogenesis, and Neutrino Mass from the $B-L$ Violation just above the Electroweak Scale

## TL;DR

This paper proposes an extension of the Standard Model with a dark sector and local $U(1)_{D}$ symmetry, explaining neutrino mass, dark matter, and baryon asymmetry through $B-L$ violation near the electroweak scale, with testable predictions.

## Contribution

It introduces a novel model linking dark matter, neutrino mass, and leptogenesis via $B-L$ violation just above the electroweak scale, unifying several phenomena.

## Key findings

- The model accounts for tiny neutrino masses.
- It explains the origin of dark matter and baryon asymmetry.
- Predictions are testable in upcoming experiments.

## Abstract

I suggest an extension of the SM by introducing a dark sector with the local $U(1)_{D}$ symmetry. The particles in the dark sector bring about the new physics beyond the SM. In particular the global $B-L$ symmetry is violated just above the electroweak scale, this becomes a common origin of the tiny neutrino mass, the cold dark mater and the baryon asymmetry. The model can not only account for the tiny neutrino mass and the "WIMP Miracle", but also achieve the leptogenesis around the electroweak scale. Finally, it is very possible that the model predictions are tested in near future experiments.
