Origins of Inert Higgs Doublets

TL;DR

This paper explores how inert Higgs doublets can naturally emerge in grand unified theories, providing a theoretical basis for their existence and discussing specific examples.

Contribution

It demonstrates that inert Higgs doublets and the required $Z_2$ symmetry can arise naturally within grand unified theories, offering a new perspective on their origin.

Findings

Inert Higgs doublets can originate from grand unified theories.

The associated $Z_2$ symmetry can occur automatically in these models.

Several explicit examples of such embeddings are discussed.

Abstract

We consider beyond the standard model embedding of inert Higgs doublet fields. We argue that inert Higgs doublets can arise naturally in grand unified theories where the necessary associated $Z_2$ symmetry can occur automatically. Several examples are discussed.
