论文摘要
轴突样颗粒（ALP）的研究通常集中在单一类型的相互作用上，例如仅与光子耦合。但是，大多数ALP模型都可以预测不同耦合之间的相关性，这些耦合以重要方式改变了现象学。例如，在高能量的标准型号玻色子上耦合的MEV尺度ALP一般会与光子，$ W^\ pm $和$ Z $玻色子以及低能能的介子和核子相互作用。我们研究了这种情况的含义，并指出天体物理的约束，尤其是从SN1987A来看，可能会大大放松，开辟了可以通过NA62等实验室实验来探索的参数空间的新区域。
Studies of axion-like particles (ALPs) commonly focus on a single type of interaction, for example couplings only to photons. Most ALP models however predict correlations between different couplings, which change the phenomenology in important ways. For example, an MeV-scale ALP coupled to Standard Model gauge bosons at high energies will in general interact with photons, $W^\pm$ and $Z$ bosons as well as mesons and nucleons at low energies. We study the implications of such scenarios and point out that astrophysical constraints, in particular from SN1987A, may be substantially relaxed, opening up new regions of parameter space that may be explored with laboratory experiments such as NA62.
