论文摘要
出色的冷却论点对各种新物理学模型都严格限制。在本文中，我们认为逃避这些约束的机制受热力学参数的限制，然后提出了最小的模型扩展，该扩展使新粒子可以逃避所有恒星的约束。在此过程中，我们证明了可以使用边缘信号和Xenon1t多余的示例来重新开放有趣的参数空间。这种机制凸显了实验室实验在良好控制的环境中寻找新物理学的重要性，这是对天体物理搜索的补充。
Stellar cooling arguments place strict restrictions on a wide variety of models of new physics. In this paper, we argue that mechanisms to evade these constraints are restricted by thermodynamic arguments, then present a minimal model extension that allows new particles to evade all stellar constraints. In doing this, we demonstrate that interesting parameter space can be reopened, using the EDGES signal and Xenon1T excess as examples. This mechanism highlights the importance of laboratory experiments in a well-controlled environment to search for new physics, complementary to astrophysical searches.
