XENON1T中的镜像暗物质和电子反冲事件

Mirror Dark Matter and Electronic Recoil Events in XENON1T

Lei Zu, Guan-Wen Yuan, Lei Feng, Yi-Zhong Fan

摘要:

最近,XENON1T实验报告了在电子反冲光谱中可能检测到过量。这样的过度可能表明新物理学的存在。在这项工作中,我们认为镜电子与普通电子通过光子$-$镜光子动力学混合与参数$ε\sim 10^{-12}(n_{\rm e'}/0.2{\rm cm^{-3}})^{-1/2}({v_{\rm c}^0/5\times 10^{9}~{\rm cm~s^{-1}}})^{1/2}$的散射可以解释过量的电子反冲事件在XENON 1T,其中$n_{\rm e'}$是镜电子的密度和$v_{\rm c}^0$是截止速度的镜电子到达地球。有趣的是,解释XENON1T电子反冲谱过剩的这个参数与Darkside50的约束是一致的。

英文摘要:

Recently, the XENON1T experiment has reported the possible detection of an excess in the electronic recoil spectrum. Such an excess may indicate the presence of new physics. In this work, we suggest that the scattering of mirror electrons with ordinary electrons through photon$-$mirror photon kinetic mixing with parameter $ε\sim 10^{-12}(n_{\rm e'}/0.2{\rm cm^{-3}})^{-1/2}({v_{\rm c}^0/5\times 10^{9}~{\rm cm~s^{-1}}})^{1/2}$ may account for the excess electronic recoil events in XENON1T, where $n_{\rm e'}$ is the density of mirror electron and $v_{\rm c}^0$ is the cutoff velocity of the mirror electron arriving at the earth. Interestingly, this parameter to interpret the excess of XENON1T electronic recoil spectrum are consistent with the constrains of Darkside50.
