摘要

在$SO（10）到SU（5）乘以U（1）\chi$的情况下，展示了如何获得拉锯狄拉克中微子。在这个框架中，$U（1）$轻子数是守恒的，利用它可以实现具有轻标量双轻子介体的自相互作用暗物质。此外，$U（1）$重子数可能被分解为（−1）3B，从而产生宇宙的重子对称性。强CP问题的轴子解也可以包含在内。

$U(1)_\chi$ and Seesaw Dirac Neutrinos

In the context of $SO(10) \to SU(5)\times U(1)\chi$, it is shown how seesaw Dirac neutrinos may be obtained. In this framework, $U(1)$ lepton number is conserved, with which self-interacting dark matter with a light scalar dilepton mediator may be implemented. In addition, $U(1)$ baryon number may be broken to (−1)3B, thereby generating a baryonasymmetry of the Universe. The axionic solution to the strong CP problem may alsobe incorporated.
