论文摘要
我们提出了一个有吸引力的模型，该模型在Xenon1t协作报告的1-5 KEV附近过多的电子后坐力事件与基于辐射的Seesaw场景的微小中微子质量很好地联系在一起。我们的暗物质（DM）是一种同源单元惰性玻色子，它在一环水平上产生非衍生中微子质量中发挥作用，并且该DM与一对单环级别的一对电子相互作用，这是解释XENON1T ANOMOLOLY所需的一环级别。还要求激发的DM和DM之间的质量差异必须是kev阶。有趣的是，小质量差异$ \ sim $ kev与中微子群众成正比。这表明我们通过微小的质量差异和一环效应进行了双重抑制。然后，我们显示一些基准点来解释异常的异常，满足了所有约束，例如Xenon1t电子的事件比率，长期寿命比宇宙的年龄更长，除了中微子振荡数据和Lepton oferations（LFVS）外，除了中微子振荡数据外，还需要遗物密度。
We propose an attractive model that excess of electron recoil events around 1-5 keV reported by the XENON1T collaboration nicely links to the tiny neutrino masses based on a radiative seesaw scenario. Our dark matter(DM) is an isospin singlet inert boson that plays an role in generating non-vanishing neutrino mass at one-loop level, and this DM inelastically interacts with a pair of electrons at one-loop level that is required to explain the XENON1T anomaly. It is also demanded that the mass difference between an excited DM and DM has to be of the order keV. Interestingly, the small mass difference $\sim$keV is proportional to the neutrino masses. It suggests that we have double suppressions through the tiny mass difference and the one-loop effect. Then, we show some benchmark points to explain the XENON1T anomaly, satisfying all the constraints such as the event ratio of electrons of XENON1T, a long lived particle be longer than the age of Universe, and relic density in addition to the neutrino oscillation data and lepton flavor violations(LFVs).
