ADMX Status

Understand

Nearly all astrophysical and cosmological data point convincingly to a large component of cold dark matter (CDM) in the Universe.

• The axion particle, first theorized as a solution to the strong charge-parity problem of quantum chromodynamics, has been established as a prominent CDM candidate.
• Cosmic observation and particle physics experiments have bracketed the unknown mass of CDM axions between approximately {\mu}eV and meV.
• The Axion Dark Matter eXperim8ent (ADMX) is a direct-detection CDM axion search which has set limits at the KSVZ coupling of the axion to two photons for axion masses between 1.9 and 3.7 {\mu}eV.
