Real CP violation in a simple extension of the standard model

TL;DR

This paper introduces a straightforward three-Higgs-doublet extension of the standard model that incorporates real CP violation, offering a potential solution to the strong CP problem.

Contribution

It proposes a novel minimal extension with three Higgs doublets that naturally induces real CP violation and addresses the strong CP problem.

Findings

Real CP violation is successfully incorporated.

The model attenuates the strong CP problem.

The extension remains minimal and simple.

Abstract

I present a simple three-Higgs-doublet extension of the standard model in which real CP violation takes place. The strong CP problem is attenuated by this model.
