我们详细描述了从耶鲁大学敏感轴子CDM （HAYSTAC）的光镜（Haloscope）获得第一极限的分析过程，HAYSTAC是一个寻找质量大于20 μ eV的冷暗物质（CDM）轴子的微波腔。我们为轴子暗物质实验（ADMX）开创的轴子搜索分析引入了几项重大创新，包括对构成轴子搜索数据集的单个功率谱进行最佳过滤，以及对这些光谱进行组合和重组的一致最大似然程序。这些创新使我们能够直接从组合数据的统计中获得排除在任何期望置信水平的轴-光子耦合竖条g（gamma）竖条。
We describe in detail the analysis procedure used to derive the first limits from the Haloscope at Yale Sensitive to Axion CDM (HAYSTAC), a microwave cavity search for cold dark matter (CDM) axions with masses above 20 mu eV. We have introduced several significant innovations to the axion search analysis pioneered by the Axion Dark Matter eXperiment (ADMX), including optimal filtering of the individual power spectra that constitute the axion search data set and a consistent maximum likelihood procedure for combining and rebinning these spectra. These innovations enable us to obtain the axion-photon coupling vertical bar g(gamma)vertical bar excluded at any desired confidence level directly from the statistics of the combined data.
