我们提出了一个非常简单的暗物质性质和中微子质量之间的关系自然出现的情况。这个框架指向一个低能量理论，其中中微子质量起源于keV-MeV质量范围内的轻标量暗物质粒子的存在。我们讨论了不同的方法来约束和测试这种情况下，通过天体物理学和宇宙学的观测以及实验室实验。最后，我们指出，一个有趣的方面是，隐含的质量范围是兼容的一个所需的解释的神秘发射的511千电子伏的光子从我们的银河系中心的暗物质湮灭到e{sup +}e{sup -}对。
We present a scenario in which a remarkably simple relation linking dark matter properties and neutrino masses naturally emerges. This framework points towards a low energy theory where the neutrino mass originates from the existence of a light scalar dark matter particle in the keV-MeV mass range. We discuss different ways to constrain and test this scenario by means of astrophysical and cosmological observations as well as laboratory experiments. Finally, we point out that one interesting aspect is that the implied mass range is compatible with the one required for the explanation of the mysterious emission of 511 keV photons from the center of our galaxy in terms of dark matter annihilation into e{sup +}e{sup -} pairs.
