Abstract

The Center for Axion and Precision Physics Research at the Institute for Basic Science is searching for axion dark matter using ultralow temperature microwave resonators. We report the exclusion of the axion mass range 10.7126-10.7186 μeV with near Kim-Shifman-Vainshtein-Zakharov (KSVZ) coupling sensitivity and the range 10.16-11.37 μeV with about 9 times larger coupling at 90% confidence level. This is the first axion search result in these ranges. It is also the first with a resonator physical temperature of less than 40 mK.

摘要

基础科学研究所的轴子与精密物理研究中心正在使用超低温微波谐振器寻找轴子暗物质。我们报告了在90%置信水平下，排除了质量范围为10.7126 - 10.7186 μeV且具有接近金-希夫曼-瓦因施泰因-扎哈罗夫（KSVZ）耦合灵敏度的轴子，以及质量范围为10.16 - 11.37 μeV且耦合约大9倍的轴子。这是在这些范围内的首个轴子搜索结果。这也是首个使用物理温度低于40 mK的谐振器的搜索结果。
