论文摘要
在具有独立打破超对称性的多种扇区的情况下，可以预测戈德斯蒂尼的多样性。我们在Xenon1T实验中观察到的2-7 KeV中的电子后坐力多余的解释是新的解释，其长寿命很长的Goldstini DM弹性地从电子中散射出来。 Goldstini DM可以通过另一个几乎退化（长寿）Goldstini DM的晚期来提高，其微小的质量差异被转化为较轻的Goldstini DM和中微子的动能。我们显示可以找到可行的参数空间，这可以解释Xenon1t实验最近报告的2-3 KEV左右的电子后坐力事件的过量。
In the scenario with a multiplicity of sectors which independently break supersymmetry, multiplicity of goldstini are predicted. We propose a new interpretation of the electron recoil excess at 2-7 keV observed in the XENON1T experiment with very long-lived goldstini DM elastically scattering off the electrons. The goldstini DM can be boosted by the late-decay of the other nearly degenerate (long-lived) goldstini DM, with their tiny mass difference being converted into kinetic energy of the lighter goldstini DM and neutrinos. We show that viable parameter space can be found which can explain the excess of electron recoil events around 2-3 keV recently reported by the XENON1T experiment.
