TL;DR

This paper introduces a left-right mirror symmetric model with specific global symmetries that explains neutrino masses, matter-antimatter asymmetry, and cold dark matter, predicting testable phenomena like right-handed neutrino asymmetry.

Contribution

The model uniquely combines left-right symmetry with global $U(1)_{B-L} imes U(1)_{D}$ symmetries to address multiple fundamental issues in particle physics.

Findings

Predicts a right-handed neutrino asymmetry

Abstract

The paper suggests a left-right mirror symmetric model with the global $U(1)_{B-L}\otimes U(1)_{D}$ symmetries. The model can simultaneously accommodate the standard model, neutrino physics, matter-antimatter asymmetry and cold dark matter. The model naturally and elegantly accounts for the origin of the tiny neutrino mass, matter-antimatter asymmetry and cold dark matter. In particular, it predicts a number of interesting results, e.g. a right-handed neutrino asymmetry and a dark Goldstone boson. It is also feasible and promising to test the model in future experiments.
