论文摘要
我们在Dine-fischler-Srednicki-Zhitnitskii敏感性上以CAPP-12B-Haloscope的速度报告了轴突暗物质搜索，假设轴占了局部暗物质密度的100 \％。 该搜索不包括轴 - Photon耦合$ g_ {aγγ} $下降至$ 6.2 \ times10^{ - 16} $ gev $^{ - 1} $在4.51和4.59 $ $ $ $ ev之间的范围为90 \％\％的置信度。 实现的实验灵敏度还可以排除Kim-Shifman-Vainshtein-Zakharov轴轴线的暗物质，该暗物质仅占局部暗物质密度的13％。 CAPP-12TB吊带板将继续在各种轴心质量上进行搜索。
We report an axion dark matter search at Dine-Fischler-Srednicki-Zhitnitskii sensitivity with the CAPP-12TB haloscope, assuming axions contribute 100\% of the local dark matter density. The search excluded the axion--photon coupling $g_{aγγ}$ down to about $6.2\times10^{-16}$ GeV$^{-1}$ over the axion mass range between 4.51 and 4.59 $μ$eV at a 90\% confidence level. The achieved experimental sensitivity can also exclude Kim-Shifman-Vainshtein-Zakharov axion dark matter that makes up just 13\% of the local dark matter density. The CAPP-12TB haloscope will continue the search over a wide range of axion masses.
