论文摘要
核心爆发的超新星中的热，富含中子和密集的情况提供了带负电的呈负电源的来源，这些普力可能构成了大部分物质的一部分。这些丰富的热蛋白可以在填充光线和隐藏的假设颗粒中发挥作用。我们通过涉及超新星培养的反应讨论了深色仪表玻色子的产生，其速率是由等异源核子偶联决定的。我们考虑了两种玩具模型，即深色光子和测量$ B-L $模型，它们在介质中带有典型的不同等异源核子偶联结构。 Pion引起的深色仪表玻色子留下了与超新星相关的几种观察后果的印记。它们相当大的发射率和特征性的硬光谱分布会导致深度仪玻色子模型的严格约束，尤其是在两个电子质量上方的质量上。
The hot, neutron-rich, and dense circumstance in core-collapse supernovae provides a source of negatively charged pions that may make up a significant portion of the matter. These abundant thermal pions can play a role to populate light and hidden hypothetical particles. We discuss the dark gauge boson production via reactions involving supernova pions, the rate of which is determined by the isovector nucleon coupling. We take into account the two toy models, the dark photon and the gauged $B-L$ models, that carry the typical distinct isovector nucleon coupling structure in the medium. Pion-induced dark gauge bosons leave an imprint on several observational consequences associated with supernova. Their sizable emissivity and characteristic hard spectral distribution result in the stringent constraints on the dark gauge boson models, in particular at masses above the two electron mass.
