氘核电蜕变成暗物质和接近阈值的质子

Electrodisintegration of Deuteron into Dark Matter and Proton Close to Threshold

A. N. Ivanov, R. Höllwieser, N. I. Troitskaya, M. Wellenzohn, Ya. A. Berdnikov

摘要:

我们讨论了调查的暗物质衰变模式的中子,提出了Fornal和Grinstein(物理评论快报。120 191801(2018))和Ivanov等人(arXiv:1806.10107 [hep-ph])通过分析氘核d电蜕变成接近阈值的暗物质费米子chi和质子p,解决了中子寿命异常问题。我们计算了反应e^- + d -> x + p + e^-的三重微分截面,并建议在符合实验中寻找这样一个暗物质通道,该实验研究了氘核e^- + d -> n + p + e^-电蜕变为中子n和接近阈值的质子,同时电子、质子和中子符合地出射。中子信号的缺失应该证明探测到了暗物质费米子。

英文摘要:

We discuss an investigation of the dark matter decay modes of the neutron, proposed by Fornal and Grinstein (Phys. Rev. Lett. 120 191801 (2018)) and Ivanov et al. ( arXiv:1806.10107 [hep-ph]) for solution of the neutron lifetime anomaly problem, through the analysis of the electrodisintegration of the deuteron d into dark matter fermions chi and protons p close to threshold. We calculate the triple-differential cross section for the reaction e^- + d ->χ+ p + e^- and propose to search for such a dark matter channel in coincidence experiments on the electrodisintegration of the deuteron e^- + d -> n + p + e^- into neutrons n and protons close to threshold with outgoing electrons, protons and neutrons in coincidence. A missing of neutron signals should testify a detection of dark matter fermions.
