Search for solar axions via axion-photon coupling with the Majorana Demonstrator

Understand

Axions were originally proposed to explain the strong-CP problem in QCD.

• Through the axion-photon coupling, the Sun could be a major source of axions, which could be measured in solid state detection experiments with enhancements due to coherent Primakoff-Bragg scattering.
• The Majorana Demonstrator experiment has searched for solar axions with a set of $^{76}$Ge-enriched high purity germanium detectors using a 33 kg-yr exposure collected between Jan.
• 2017 and Nov.
