论文摘要
我们讨论了一个模型，该模型可以容纳$ b $ physics异常，以结合两个标量leptoquarks，$ r_2 $和$ s_3 $，质量$ \ mathcal {o}（1 \，\，\ Mathrm {tev}）$，以及我们在以前的论文中提出了这一点。我们更新了其参数空间的分析，并表明模型仍然可行，并且与许多低能和高能量风味物理限制一致。由于该模型预测了一个非零的新物理阶段，因此我们讨论了测试其对中子电偶极矩的贡献以及对独家$ b \ tocτ\barν$衰减的角度分布的可能性。我们发现该模型可以为$ \ MATHCAL {B}（b \ to K^{（\ ast）}ννν）$提供显着的增强，并同时将上限和下限提供到$ \ Mathcal {b}（b \ to K^{（\ ast）}μτ）$。
We discuss a model that can accommodate the $B$-physics anomalies, based on combining two scalar leptoquarks, $R_2$ and $S_3$, of mass $\mathcal{O}(1\,\mathrm{TeV})$, and that we proposed in our previous paper. We update the analysis of its parameter space and show that a model remains viable and consistent with a number of low energy and high energy flavor physics constraints. Since the model predicts a non-zero New Physics phase, we discuss the possibility to test its contribution to the neutron electric dipole moment and to the angular distributions of the exclusive $b\to cτ\bar ν$ decays. We find that the model can provide a significant enhancement to $\mathcal{B}(B\to K^{(\ast)}νν)$ and provides both the upper and lower bounds to $\mathcal{B}(B\to K^{(\ast)}μτ)$.
