我们研究了直接暗物质探测实验在U（1）B− L和U（1）R模型中发现无菌中微子暗物质衰变产物的可能性。这是可能的，如果不育中微子与轻规范玻色子相互作用，并衰变为中微子和轻规范玻色子具有一定的寿命。这种衰变产生的高能中微子在直接暗物质探测实验中具有足够大的反冲能量，被原子核散射。我们强调，直接暗物质探测实验不仅可以探索WIMP，但也不育中微子暗物质。
We examine the possibility that direct dark matter detection experiments find decay products from sterile neutrino dark mater in U (1) B− L and U (1) R models. This is possible if the sterile neutrino interacts with a light gauge boson, and decays into a neutrino and the light gauge boson with a certain lifetime. This decay produces energetic neutrinos scattering off nuclei with a large enough recoil energy in direct dark matter detection experiments. We stress that direct dark matter detection experiments can explore not only WIMP but also sterile neutrino dark matter.
