QCD（量子色动力学）轴子成为最有动机的暗物质候选者之一。2018年，美国能源部“第二代”旗舰暗物质项目之一的轴子暗物质实验（ADMX）首次展示了在小频率范围内对高度可信的“DFSZ”暗物质轴子耦合的敏感性。我们预计，这一进展标志着构建更强大的实验的第一步，这些实验可以以高灵敏度探索大面积的轴子参数空间并产生发现。但是，实现这一点需要我们对理论和实验设计的理解的进步。在2021年1月25日至1月27日期间，举行了“超越第二代轴子研讨会”，其中选定的社区成员讨论了我们对QCD轴子的广泛理解，并为灵敏度和质量达到远远超出当前“第二代”实验的未来实验制定了路线。这些会议记录是所提出和讨论的主题的摘要。
The QCD (Quantum ChromoDynamics) axion emerged as one of the best-motivated dark matter candidates. In 2018, the Axion Dark Matter eXperiment (ADMX), one of the U.S. Department of Energy’s “Gen 2” flagship dark-matter projects, demonstrated first sensitivity to the highly plausible “DFSZ” dark matter axion couplings over a small frequency range. We anticipate this development marks the first step in constructing yet more powerful experiments that can explore large swaths of the axion parameter space at high sensitivity and result in a discovery. But, realizing this requires advances in both our understanding of the theory and experiment design. Between 25 January and 27 January 2021, the “Axions Beyond Gen 2 Workshop” was held, where selected members of the community discussed our broad understanding of the QCD axion and charted a course for future experiments having sensitivity and mass reach well beyond the current “Gen 2” experiments. These proceedings are summaries of the topics presented and discussed.
