在扩展标准模型的基础上，我们构造了Dirac中微子质量产生的单圈和双圈暗生模型。结果表明，在无反常条件下，中间费米子单态的总数是唯一固定的，新粒子可能带有外来电荷，从而使直接SM Yukawa质量项和Majorana质量项自然地被禁。对称性自发破缺后，离散对称性以剩余对称性的形式出现，并导致中间场作为DM候选场的稳定性。轻子味破坏，DM，leptogenesis和LHC签名的唯象方面进行了讨论。
We construct the one-loop and two-loop scotogenic models for Dirac neutrino mass generation in the context ofextensions of standard model. It is indicated that the total number of intermediate fermion singlets is uniquely fixed by the anomaly free condition and the new particles may have exoticcharges so that the direct SM Yukawa mass termand the Majorana mass termare naturally forbidden. After the spontaneous breaking of thesymmetry, the discreteorsymmetry appears as the residual symmetry and gives rise to the stability of intermediate fields as DM candidates. Phenomenological aspects of lepton flavor violation, DM, leptogenesis and LHC signatures are discussed.
