Search for axioelectric effect of solar axions using BGO scintillating bolometer

A search for axioelectric absorption of solar axions produced in the (Formula presented.) reaction has been performed with a BGO detector placed in a low-background setup. A model-independent limit on the combination of axion-nucleon and axion-electron coupling constants has been obtained: (Formula presented.) for 90 % confidence level. The constraint of the axion-electron coupling constant has been obtained for hadronic axion with masses of (0.1-1) MeV: (Formula presented.). © 2014 The Author(s)

Axion Dark Matter

Axions are well-motivated dark matter candidates with simple cosmological production mechanisms. They were originally introduced to solve the strong CP problem, but also arise in a wide range of extensions to the Standard Model. This Snowmass white paper summarizes axion phenomenology and outlines next-generation laboratory experiments proposed to detect axion dark matter. There are vibrant synergies with astrophysical searches and advances in instrumentation including quantum-enabled readout, high-Q resonators and cavities and large high-field magnets. This white paper outlines a clear roadmap to discovery, and shows that the US is well-positioned to be at the forefront of the search for axion dark matter in the coming decade.Axions are well-motivated dark matter candidates with simple cosmological production mechanisms.
