论文摘要
由于轴突质量未知，轴突卤素搜索中最重要，最实用的功绩之一是扫描速率。在最佳的实验参数下，提高功绩数字的唯一方法是增加轴突悬垂搜索分析程序中实验设计的信号与噪声比。在本文中，我们使用CAPP-8TB Haloscope获取的数据报告了改进的轴突卤素搜索分析。通过在存在轴突信号的情况下校正背景参数偏置的背景，我们意识到信号与噪声比效率约为100 \％。鉴于迄今为止的轴突卤素搜索分析，扫描速率可以提高21 \％，信号与噪声比的提高约为10 \％。这种改进是Axion Haloscope搜索中的另一个低成本创新，其中所有实验参数目前都处于最佳状态。
One of the most significant and practical figures of merit in axion haloscope searches is the scanning rate, because of the unknown axion mass. Under the best experimental parameters, the only way to improve the figure of merit is to increase the experimentally designed signal to noise ratio in the axion haloscope search analysis procedure. In this paper, we report an improved axion haloscope search analysis using the data taken by the CAPP-8TB haloscope. By correcting for the background biased by the background parametrizations in the presence of axion signals, we realized a signal to noise ratio efficiency of about 100\%. Given the axion haloscope search analyses to date, the scanning rate can be improved by 21\%, with about a 10\% improvement in the signal to noise ratio. This improvement is another low cost innovation in axion haloscope searches, where all the experimental parameters are currently at their best.
