论文摘要
最近的实验结果与其各自的标准模型预测(称为风味异常)之间存在差异,在半衰减充电和中性电流$ b $ - 定期,MUON磁矩$(G-2)_μ$以及凸起角度的提取。在此程序中,我们回顾了两个新的物理模型,它们在TEV量表上介绍了两个标量介质,并旨在对风味异常的综合解释。第一款型号具有leptoquarks $ s_1 $和$ s_3 $,并为$ b $ - andemalies和单循环级别提供了树级解决方案,也可以为异常$(G-2)_μ$ $ $。第二个具有Leptoquark $ s_1 $和带电的Singlet $ ϕ^+$。尽管$ s_1 $提供了与第一型型号相同的带电电流$ b $ - $ - $ ANOMALY和$(g-2)_ $的解决方案,但$ ϕ^+$可以独立地容纳Cabibbo-angle Anomaly,并与$ s_1 $一起解决中性$ B $ b $ $ b $ - y-Anomomaly in One-loop。
Discrepancies between recent experimental results and their respective Standard Model predictions, known as flavour anomalies, are reported in semileptonic charged and neutral-current $B$-decays, the muon magnetic moment $(g-2)_μ$, and the extraction of the Cabibbo angle. In this proceedings, we review two New Physics models that introduce two scalar mediators at the TeV scale and aim at a combined explanation of the flavour anomalies. The first model features the leptoquarks $S_1$ and $S_3$ and provides tree level solutions to both $B$-anomalies and one-loop level solution to the anomalous $(g-2)_μ$. The second features the leptoquark $S_1$ and the charged singlet $ϕ^+$. While $S_1$ provides the same solution to the charged-current $B$-anomaly and $(g-2)_μ$ as in the first model, $ϕ^+$ can accommodate the Cabibbo-angle anomaly independently and together with $S_1$ can resolve the neutral-current $B$-anomaly at one-loop.
