Can Axions Save The Universe?
Can axions save the universe? The hunt for dark matter is shifting from particles to waves named after a laundry detergent. The search is on for some of the flimsiest lumps of matter and energy. For decades, scientists have been on a quest to uncover the mysterious particles that compose dark matter. One of the most promising candidates is the axion, an elusive.
We then discuss how the axion emerges as a dark matter candidate, and how it is produced in the early universe. The symmetry properties of the axion dictate the form of its interactions with ordinary matter.
