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.

辐射中微子模型中的狄拉克暗物质

我们提出了一个带有狄拉克暗物质候选物的简单辐射中微子质量情景,这是通过最小限度地实现 ž3对称。我们介绍了两个狄拉克中微子和两个惰性双峰。我们证明该模型具有一个较大的允许区域,该区域可以满足中微子振荡数据,轻子风味违规,暗物质的直接/间接检测和暗物质残留密度的约束。我们还提出了中微子Yukawa耦合的有效参数化方法,该方法可重现所需的有效中微子质量矩阵。
