论文摘要
如果提议的Leptoquarks解释了在$ b $ -Meson衰减中观察到的有趣的异常，则$ r_ {d^{（\ ast）} $和$ r_ {k^{（\ ast）}} $，以及在emp of muon can $（g-2）中，中微子模型，所有这些风味异常，以及中微子肿块的起源以及暗物质的性质，都可能在统一的图片中解决。在最小的锯，一环和两环实现之中候选人。在这些Leptoquarks与可以适应所有风味异常的人进行了简单的匹配之后，我们建立了嵌入了Leptoquarks的Scotogenic Dirac Neutrino模型，该模型可以解决上述所有问题。
If the leptoquarks proposed to account for the intriguing anomalies observed in the $B$-meson decays, $R_{D^{(\ast)}}$ and $R_{K^{(\ast)}}$, as well as in the anomalous magnetic moment of the muon, $(g-2)_μ$, can be embedded into the scotogenic Dirac neutrino model, all these flavor anomalies, together with the origin of neutrino masses and the nature of dark matter, would be potentially addressed in a unified picture. Among the minimal seesaw, one-loop, and two-loop realizations of the dimension-4 effective operator $\mathcal{L}_{4}$ for the Dirac neutrino masses, we show that plenty of diagrams associated with the two-loop realizations of $\mathcal{L}_{4}$ can support the coexistence of leptoquarks and dark matter candidates. After a simple match of these leptoquarks to those that can accommodate all the flavor anomalies, we establish the scotogenic Dirac neutrino models embedded with leptoquarks, which could address all the problems mentioned above.
