论文摘要
In this work, we present a solution to the persistent tensions in the decay observables $R_{D^{(\ast)}}$ and $R_{K^{(\ast)}}$ by introducing a $SU(2)_L$ doublet and a $SU(2)_L$ triplet scalar leptoquarks (LQs) that reside at the TeV energy scale.在标准模型中保持无质量的中微子通过环路内的同一LQS的传播在单循环水平上自然而然地接受。显然是不相交的现象学观察的这种常见起源很有吸引力,我们对该设置进行了全面的分析。我们确定了适应这些风味异常所需的最小Yukawa纹理,并成功地纳入了中微子振荡数据,同时与所有实验性约束一致。这种情况有可能在实验中测试未来,以改进了违反Lepton风味的过程的测量。此外,对这些风味异常的适当解释可以预测LHC可以直接访问的TEV量表LQ。
In this work, we present a solution to the persistent tensions in the decay observables $R_{D^{(\ast)}}$ and $R_{K^{(\ast)}}$ by introducing a $SU(2)_L$ doublet and a $SU(2)_L$ triplet scalar leptoquarks (LQs) that reside at the TeV energy scale. Neutrinos that remain massless in the Standard Model receive naturally small masses at one-loop level via the propagation of the same LQs inside the loop. Such a common origin of apparently disjoint phenomenological observations is appealing, and we perform a comprehensive analysis of this set-up. We identify the minimal Yukawa textures required to accommodate these flavor anomalies and to successfully incorporate neutrino oscillation data while being consistent with all experimental constraints. This scenario has the potential to be tested at the experiments by the future improved measurements in the lepton flavor violating processes. Furthermore, proper explanations of these flavor anomalies predict TeV scale LQs that are directly accessible at the LHC.
