论文摘要
在这项工作中，研究了针对新型暗物质（DM）直接检测方法，对双β衰减不稳定的核进行了研究。特别是，将考虑负责中微子双β衰变的图表，以用于在双β不稳定核上散射的主要DM Fermion的检测技术，从而刺激其衰变。刺激的双β衰变的放热性质将允许直接检测光DM费米，这是一类DM候选者，这些DM候选者很难或不可能使用传统的弹性散射技术进行调查。显示了不同DM质量的预期信号分布以及核散射横截面的上限，并将其与$^{136} $ XE核的现有数据进行了比较。
Nuclei that are unstable with respect to double beta decay are investigated in this work for a novel Dark Matter (DM) direct detection approach. In particular, the diagram responsible for the neutrinoless double beta decay will be considered for the possible detection technique of a Majorana DM fermion inelastically scattering on a double beta unstable nucleus, stimulating its decay. The exothermic nature of the stimulated double beta decay would allow the direct detection also of a light DM fermion, a class of DM candidates that are difficult or impossible to investigate with the traditional elastic scattering techniques. The expected signal distribution for different DM masses and the upper limits on the nucleus scattering cross sections, are shown and compared with the existing data for the case of $^{136}$Xe nucleus.
