Axions as Dark Matter Particles

TL;DR

This paper reviews the role of axions as dark matter candidates, discussing theoretical motivation, models, experimental constraints, and ongoing searches, emphasizing future prospects like the ADMX experiment.

Contribution

It provides a comprehensive overview of axion dark matter, highlighting recent developments and future experimental efforts to detect axions.

Findings

Axions remain a strong dark matter candidate.

Future experiments like ADMX will explore significant parameter space.

Current constraints do not exclude axions as dark matter.

Abstract

We review the current status of axions as dark matter. Motivation, models, constraints and experimental searches are outlined. The axion remains an excellent candidate for the dark matter and future experiments, particularly the Axion Dark Matter eXperiment (ADMX), will cover a large fraction of the axion parameter space.
