论文摘要
我们对$ s_1 $和$ s_3 $ lepto-Quarks的低能现象学进行了完整的研究，旨在解决$ b $ -Meson衰变和MUON磁性偶极力矩的观察到的偏差。在有效的现场理论方法中，使用这些LeptoQuarks与标准模型有效田间理论的最新一环匹配，在有效的现场理论方法中以一环准确性计算对观测值的效果。我们提出几种情况，在每种情况下讨论首选参数空间和最相关的可观察结果。
We perform a complete study of the low-energy phenomenology of $S_1$ and $S_3$ lepto-quarks, aimed at addressing the observed deviations in $B$-meson decays and the muon magnetic dipole moment. Leptoquark contributions to observables are computed at one-loop accuracy in an effective field theory approach, using the recently published complete one-loop matching of these leptoquarks to the Standard Model effective field theory. We present several scenarios, discussing in each case the preferred parameter space and the most relevant observables.
