介绍DMRadio-GUT，搜索GUT尺度的QCD轴子
Introducing DMRadio-GUT, a search for GUT-scale QCD axions
摘要：
量子色动力学轴子是一个领先的暗物质候选者，它是标准模型中强CP问题解决方案的一部分。轴子与光子的耦合是最常见的实验探测，但许多参数空间尚未探索。QCD轴子与标准模型的耦合与轴子质量成线性比例，因此，高激发区域0.4-120 neV，对应于大统一理论尺度的轴子，特别难以达到。本文介绍了一个确定的搜索大统一体尺度的轴子的设计要求，并回顾了技术进步，使这一计划。
英文摘要：
The QCD axion is a leading dark matter candidate that emerges as part of the solution to the strong CP problem in the Standard Model. The coupling of the axion to photons is the most common experimental probe, but much parameter space remains unexplored. The coupling of the QCD axion to the Standard Model scales linearly with the axion mass; therefore, the highly-motivated region 0.4-120 neV, corresponding to a GUT-scale axion, is particularly difficult to reach. This paper presents the design requirements for a definitive search for GUT-scale axions and reviews the technological advances needed to enable this program.
