 International Axion Observatory

The International Axion Observatory (IAXO) is a proposed scientific facility designed to search for axions, hypothetical particles that are predicted by certain extensions of the Standard Model of particle physics, specifically in theories that address issues such as dark matter and the strong CP problem in quantum chromodynamics. Axions are extremely light and weakly interacting particles, making their detection quite challenging. The concept behind IAXO involves using a type of experiment known as a "light shining through walls" setup.
