# High-scale baryogenesis with testable neutron-antineutron oscillation and dark matter

## TL;DR

This paper introduces a novel high-scale baryogenesis model that predicts observable neutron-antineutron oscillations and incorporates dark matter, involving new heavy scalars and fermions beyond the Standard Model.

## Contribution

It presents a new scenario linking high-scale baryogenesis with testable neutron-antineutron oscillations and dark matter, involving specific new particles and interactions.

## Key findings

- Predicts neutron-antineutron oscillation at a testable level
- Provides a mechanism for high-scale baryogenesis
- Integrates dark matter candidate within the model

## Abstract

We propose a new scenario for predicting a one-loop neutron-antineutron oscillation at a testable level, meanwhile, realizing a thermal or inflationary baryogenesis at a very high scale. Besides the standard model content, this scenario involves two real singlet scalars with very heavy masses, two color-triplet and iso-singlet scalars at the TeV scale, as well as a Majorana singlet fermion for a dark matter candidate.
