论文摘要
通用轴突样粒子（ALP）的有效田间理论（EFT）具有许多自由参数，并且为预期的现象学留下了很大的自由。在这项工作中，我们通过为ALP执行类似轴突的真实属性来设置更多受限的EFT。确实，尽管QCD轴的Peccei-quinn对称性是异常的，但它是如此特定的方式，并且显示为量规玻色子和费米昂耦合之间的一致性条件。我们建议在通用ALP EFT上实施从DFSZ和KSVZ方案启发的这种情况。然后，这些真正类似轴突的ALP EFT特别适合作为基准场景，可用于在山脉和低能实验中寻找阿尔卑斯山。
The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology. In this work, we set up more constrained EFTs by enforcing true axion-like properties for the ALP. Indeed, though the Peccei-Quinn symmetry of the QCD axion is anomalous, it is so in specific ways, and this shows up as consistency conditions between the gauge boson and fermion couplings. We propose to enforce such conditions, as inspired from the DFSZ and KSVZ scenarios, on the generic ALP EFTs. These truly axion-like ALP EFTs are then particularly well-suited as benchmark scenarios, to be used in the search for ALPs both at colliders and at low-energy experiments.
