论文摘要
最近，Xenon1T实验报告了电子后坐力事件的过量。多余的与3KeV玻色粒暗物质的吸收的解释是一致的，例如，隐藏的光子暗物质与$ 10^{ - 15} $的动力学混合。我们指出，最小引力的产生提供了一种可行的机制，可以获得正确的遗物隐藏光子丰度。我们介绍了隐藏光子暗物质丰度在通货膨胀刻度上的参数依赖性$ h _ {\ rm inf} $以及加热温度$ t _ {\ rm rm r} $。我们表明，通货膨胀的哈勃尺度和重新加热温度都从下方界定，$ h _ {\ rm inf} \ gtrsim 7 \ times 10^{11} $ gev，$ t _ {\ rm rm r} \ rm r} \ gtrsim 10^2 $ gtrsim。特别是，高规模通胀与3KeV隐藏的光子暗物质一致。
Recently, the XENON1T experiment has reported an excess in the electronic recoil events. The excess is consistent with the interpretation of absorption of 3keV bosonic dark matter, for example, hidden photon dark matter with kinetic mixing of the order of $10^{-15}$. We point out that the minimally gravitational production provides a viable mechanism for obtaining a correct relic hidden photon abundance. We present parameter dependence of the hidden photon dark matter abundance on the inflationary scale $H_{\rm inf}$ and also the reheating temperature $T_{\rm R}$. We show that the inflationary Hubble scale and reheating temperature are both bounded from below, $H_{\rm inf}\gtrsim 7\times 10^{11}$GeV, $T_{\rm R}\gtrsim 10^2$GeV. In particular, the high-scale inflation is consistent with 3keV hidden photon dark matter.
