中微子探测器上微弱的中微子入口暗物质

Feeble neutrino portal dark matter at neutrino detectors

Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal

摘要:

我们探讨中微子门户暗物质(DM)在其最低的领域内容有两个暗扇区粒子耦合到右手中微子。假设它们与标准模型(SM)粒子的相互作用的微弱性质,我们分析了冻结生产的观察到的DM遗物密度的特征在于三个不同的类别取决于主要的生产机制。该门户网站提供了有趣的签名中微子探测器,如KamLAND,Super-Kamiokande和IceCube,从一个非常晚的标量DM衰变到费米子DM和SM中微子。这种来自宇宙和星系起源的中微子通量谱可以在未来的实验中产生异常信号。

英文摘要:

We explore the neutrino portal dark matter (DM) at its minimum of field content having two dark sector particles coupled to a right-handed neutrino. Assuming the feeble nature of their interactions with the standard model (SM) particles, we analyze the freeze-in production of the observed DM relic density characterized by three different categories depending on the major production mechanisms. The portal provides interesting signatures at the neutrino detectors like KamLAND, Super-Kamiokande and IceCube, from a very late decay of the scalar DM to the fermion DM and the SM neutrino. Such neutrino flux spectrum from the cosmic and galactic origins can produce anomalous signals at future experiments.
