论文摘要
SEESAW机制通过存在非常重的主要质量来解释中微子质量的独家质量，并导致Majoraana颗粒的出现和直接的Lepton数量违规。作者提出了一种seesaw场景，该场景仅产生同样违规的狄拉克中微子。对于具有非扰动希格斯玻色子H耦合的重中微子来说，这种情况似乎可能是可能的。这种情况可以在描述Quarks和Leptons弱混合矩阵的结构中，通过存在标准模型费米子的非常重的镜像类似物的结构。问题的非扰动性阻碍了分析解决方案，但是得出的条件表明所考虑的机制优先生成狄拉克中微子。如果所有现有的中微子都属于狄拉克类型，则这种现象可能与瘦化过程相关。
The seesaw mechanism explains the exclusive smallness of neutrino masses by the presence of very heavy Majorana masses and leads to the appearance of Majorana particles and to the direct lepton number violation. The author proposes a seesaw scenario that produces only Dirac neutrinos with the same violation. This scenario appears possible for heavy neutrinos with non-perturbative Higgs boson H couplings. Such a scenario could be accomplished in the model describing the structure of weak mixing matrices for quarks and leptons through the existence of very heavy mirror analogs of Standard Model fermions. The non-perturbativity of the problem hinders the analytical solution, but the conditions derived indicate that the mechanism under consideration preferentially generates only Dirac neutrinos. This phenomenon may have relevance for leptogenesis processes if all existing neutrinos turn out to be of the Dirac type.
