论文摘要
最近，Xenon1T实验报告了可能检测到电子后坐力光谱中的过量。这样的过剩可能表明存在新物理学。在这项工作中，我们建议将带有普通电子的镜像通过光子$ - $镜像光子光子动力子与参数混合与参数$ε\ sim \ sim 10^{ - 12} { - n _ {\ rm e'}/0.2 10^{9}〜{\ rm cm〜s^{ - 1}}}）^{1/2} $可以解释Xenon1t中的过剩电子后坐力事件，其中$ n _ {\ rm e'} $是镜像电子的密度和$ v _ {\ rm c}^0 $ rifer at of cutoff of cuteft of cuteft of cutive of cuteft of cut of cut vel。有趣的是，该参数解释了Xenon1t电子后坐力光谱的过量，与Darkside50的约束一致。
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.
