论文摘要
异种1T中的低能电子后坐力光谱为潜在的新物理学提供了有趣的提示。同时，与标准模型粒子含量的预期相比，对水平分支恒星的观察有利于存在少量额外冷却。在本说明中，我们认为一个隐藏的光子质量为$ \ sim 2.5 $ kev和$ \ sim 10^{ - 15} $的动力学混合允许对这两个过剩的质量非常适合。在这种情况下，Xenon1t中检测到的信号是由于隐藏光子暗物质颗粒的吸收，而水平分支星星的异常冷却是由于恒星内部的隐藏光子的共鸣产生。
The low-energy electronic recoil spectrum in XENON1T provides an intriguing hint for potential new physics. At the same time, observations of horizontal branch stars favor the existence of a small amount of extra cooling compared to the one expected from the Standard Model particle content. In this note, we argue that a hidden photon with a mass of $\sim 2.5$ keV and a kinetic mixing of $\sim 10^{-15}$ allows for a good fit to both of these excesses. In this scenario, the signal detected in XENON1T is due to the absorption of hidden photon dark matter particles, whereas the anomalous cooling of horizontal branch stars arises from resonant production of hidden photons in the stellar interior.
