The Principle and Detection Progress of Axion Dark Matter

Abstract

Detection of the axion is a significant yet challenging discovery for particle physics and astrophysics. Based on information retrieval and interpretation of results, a summary of state-of-art detection methods could be achieved, and future progress and be predicted. Although the axion suffices for its properties of hidden nature and impact on gravity, which leads to the difficulty of detection. There are currently several candidates for the detection of axions: cavity microwave experiments, solar axion searches, and radio telescope searches. With progress on all of these detection methods, analysis can be performed to establish a foundation for further development in these detection methods. If current methods continue to become more efficient and new methods are continuously proposed, the axion’s detection can be hastened and proof or counter-proof would be established quicker. Overall, these results offer a guideline for further axion search and newer questions based on the axion in the near future.
