Summary
This award is funded in part under the American Rescue Plan Act of 2021 (Public Law 117-2). The nature of dark matter is one of the most fundamental open questions of modern science. As searches for the dark matter have advanced, axions - that arise naturally from model solutions of what is known as the strong-CP problem - and axion-like particles have emerged as particularly compelling candidates. The search for these particles opens an experimental window into physics at ultra-high energy scales, up to the Planck-scale, and discovery of axion-like dark matter would provide potential insi
