论文摘要
最初建议轴上解释QCD中的强CP问题。通过轴 - 光子耦合，太阳可以是轴的主要来源，可以在固态检测实验中测量，并通过相干primakoff-bragg散射而增强。 Majorana示威者实验已经搜索了一组$^{76} $ ge-ge-富集的高纯族检测器，使用33 kg-yr的暴露在2017年1月至2019年11月之间收集的暴露。 GEV $^{ - 1} $（95％C.I.），用于质量高达100 eV/$ c^2 $的轴。这改善了大约1 ev/$ c^2 $和100 ev/$ c^2 $之间的基于实验室的限制。
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. 2019. A temporal-energy analysis gives a new limit on the axion-photon coupling as $g_{aγ}<1.45\times 10^{-9}$ GeV$^{-1}$ (95% C.I.) for axions with mass up to 100 eV/$c^2$. This improves laboratory-based limits between about 1 eV/$c^2$ and 100 eV/$c^2$.
