论文摘要
我们重点介绍了与QCD轴，类似轴突的颗粒和放松理论中质量和自然问题相关的一般问题。我们显示了普朗克抑制的操作员的存在，通常导致轴与标准模型的标量耦合。我们提出了一个新的$ \ mathbb z_ {n} $ QCD放松模型的新类，该模型可以解决QCD放松CP问题及其质量问题。这种新的模型还导致有趣的实验签名，可以在Precision Frontier上搜索。
We highlight general issues associated with quality and naturalness problems in theories of light QCD-axions, axion-like particles, and relaxions. We show the presence of Planck-suppressed operators generically lead to scalar coupling of axions with the Standard model. We present a new class of $\mathbb Z_{N}$ QCD relaxion models that can address both the QCD relaxion CP problem as well as its quality problem. This new class of models also leads to interesting experimental signatures, which can be searched for at the precision frontier.
