我们提出了一个新的机制来解释中微子质量与轻子数守恒，狄拉克中微子质量产生在两个循环的水平涉及暗物质候选人。在这个模型中，希格斯玻色子的轻子味违反衰变的分支比可以远大于带电轻子的轻子味违反衰变的分支比。如果在未来的对撞机实验中观察到希格斯玻色子的轻子味违反衰变，而没有检测到带电轻子的轻子味违反衰变，那么以前提出的小中微子质量的大多数模型都被排除在外，而我们的模型仍然可以生存。我们表明，该模型可以是可行的约束下，从目前的数据中微子实验，搜索轻子味违反衰变的带电轻子和暗物质实验。
We propose a new mechanism to explain neutrino masses with lepton number conservation, in which the Dirac neutrino masses are generated at the two-loop level involving a dark matter candidate. In this model, branching ratios of lepton flavor violating decays of the Higgs boson can be much larger than those of lepton flavor violating decays of charged leptons. If lepton flavor violating decays of the Higgs boson are observed at future collider experiments without detecting lepton flavor violating decays of charged leptons, most of the models previously proposed for tiny neutrino masses are excluded while our model can still survive. We show that the model can be viable under constraints from current data for neutrino experiments, searches for lepton flavor violating decays of charged leptons and dark matter experiments.
