论文摘要
我们考虑了深色光子介导的非弹性暗物质的一种新颖情况,以解释其发光功能所暗示的白矮人冷却过量,以及Xenon1t的电子后坐力事件中的过量。在阳光下,深色的光子$ a'$主要是通过热过程生产的,并且较重的暗物质$χ_2$是由Halo Dark Matter的散射$χ_1$用电子产生的。 Xenon1t信号主要由太阳能$ a'$散射产生,而白矮人的$ a'$排放可容纳额外的冷却,同时保持与其他恒星冷却观测值的一致性。还需要在Xenon1t检测器中的trium分量。我们显示了解释Xenon1t数据的参数,但没有显示白矮人冷却异常,可以将第二个信号峰埋在Xenon1t数据中,并且可在Xenonnt显示。但是,给出频谱中双峰的参数与水平分支星星的约束不相容。
We consider a novel scenario of dark photon-mediated inelastic dark matter to explain the white dwarf cooling excess suggested by its luminosity function, and the excess in electron recoil events at XENON1T. In the Sun, the dark photon $A'$ is produced mainly via thermal processes, and the heavier dark matter $χ_2$ is produced by the scattering of halo dark matter $χ_1$ with electrons. The XENON1T signal arises primarily by solar $A'$ scattering, and $A'$ emission by white dwarfs accommodates the extra cooling while maintaining consistency with other stellar cooling observations. A tritium component in the XENON1T detector is also required. We show for parameters that explain the XENON1T data, but not the white dwarf cooling anomaly, that a second signal peak may be buried in the XENON1T data and revealable at XENONnT. However, the parameters that give the double peak in the spectrum are incompatible with constraints from horizontal branch stars.
