Query: An Improved RF Cavity Search for Halo Axions   The axion is a hypothetical elementary particle and cold dark matter
candidate. In this RF cavity experiment, halo axions entering a resonant cavity
immersed in a static magnetic field convert into microwave photons, with the
resulting photons detected by a low-noise receiver. The ADMX Collaboration
presents new limits on the axion-to-photon coupling and local axion dark matter
halo mass density from a RF cavity axion search in the axion mass range 1.9-2.3
microeV, broadening the search range to 1.9-3.3 microeV. In addition, we report
first results from an improved analysis technique.
