What is an Axion?
An axion is a hypothetical elementary particle that is postulated as a solution to the problem of why the strong nuclear force violates CP symmetry. Axions are particles that are extremely light and weakly interacting, making them difficult to detect.
Properties of Axions
- Very low mass
- Weakly interacting
- Stable
Axion Case Studies
One of the most famous examples of axions is their role in solving the strong CP problem in quantum chromodynamics. Axions have also been proposed as a candidate for dark matter, although their properties make them difficult to detect.
Axion Statistics
While axions have not yet been observed directly, researchers continue to search for evidence of their existence. Theoretical models predict that axions could make up a significant portion of the dark matter in the universe.
