论文摘要
我们提出了一个简单的辐射性中微子质量场景，其中有狄拉克暗物质候选者，该场景通过Z3对称性最小化。我们介绍了两个狄拉克中微子和两个惰性双线。我们证明该模型具有一个较大的允许区域，可满足中微子振荡数据的约束，违反Lepton风味，直接/间接检测暗物质和暗物质遗物密度。我们还提出了中微子Yukawa耦合的有效参数化，该耦合重现了所需的活动中微子质量基质。
We propose a simple radiative neutrino mass scenario with a Dirac dark matter candidate, which is minimally realized by a Z3 symmetry. We introduce two Dirac neutrinos and two inert doublets. We demonstrate that the model has a large allowed region that satisfies the constraints from neutrino oscillation data, lepton flavor violations, direct/indirect detection of dark matter and dark matter relic density. We also propose an efficient parameterization of the neutrino Yukawa couplings, which reproduces a desired active neutrino mass matrix.
