Explore the intriguing possibility that axions—hypothetical particles proposed to solve the strong CP problem in quantum chromodynamics—could constitute the elusive dark matter making up approximately 85% of the universe's mass. Delve into theoretical models suggesting axions were produced in the early universe through mechanisms like the misalignment mechanism, resulting in a cold, nonrelativistic population consistent with dark matter characteristics. Discover ongoing experimental efforts, such as the Axion Dark Matter Experiment (ADMX), which aims to detect axions by observing their conversion into microwave photons in strong magnetic fields.
Join us as we unravel the potential of axions to address fundamental questions in particle physics and cosmology.
