Dirac neutrinos and anomaly-free discrete gauge symmetries

TL;DR

This paper explores how assuming neutrinos are Dirac particles enables the existence of numerous anomaly-free discrete gauge symmetries in the Supersymmetric Standard Model, including some compatible with Grand Unified Theories.

Contribution

It demonstrates the infinite possibilities of anomaly-free discrete gauge symmetries under the Dirac neutrino assumption, expanding the model-building landscape.

Findings

Infinite anomaly-free discrete symmetries are possible with Dirac neutrinos.

Some of these symmetries are compatible with GUT frameworks.

The approach broadens the scope for supersymmetric model extensions.

Abstract

Relying on Dirac neutrinos allows an infinity of anomaly-free discrete gauge symmetries to be imposed on the Supersymmetric Standard Model, some of which are GUT-compatible.
