论文摘要
尽管轴突样颗粒（阿尔卑斯山）是流行的暗物质候选者，但它们的质量产生机制以及宇宙的热发展尚不清楚。在这封信中，我们提出了在II型SEESAW机制的存在下Electroweak相变期间ALP的新质量生成机制。由于ALP在Electroweak量表上具有唯一的质量，因此ALP振荡温度与特定的ALP质量无关，这是此情况的独特特征。 ALP伴侣与活跃的中微子伴侣，在密集的ALP环境中留下了中微子振荡作为吸烟枪的效果。作为副产品，TEV规模的II Seesaw也引用了CDF合作观察到的最近$ W $ -BOSON质量异常。我们解释了三种新的物理现象，其中有一个中风。
Although axion-like particles (ALPs) are popular dark matter candidates, their mass generation mechanisms as well as cosmic thermal evolutions are still unclear. In this letter, we propose a new mass generation mechanism of ALP during the electroweak phase transition in the presence of the type-II seesaw mechanism. As ALP gets mass uniquely at the electroweak scale, there is a cutoff scale on the ALP oscillation temperature irrelevant to the specific mass of ALP, which is a distinctive feature of this scenario. The ALP couples to the active neutrinos, leaving the matter effect of neutrino oscillations in a dense ALP environment as a smoking gun. As a by-product, the recent $W$-boson mass anomaly observed by the CDF collaboration is also quoted by the TeV-scale type-II seesaw. We explain three kinds of new physics phenomena are with one stroke.
