论文摘要
我们讨论了Lepton风味普遍性的当前状态，可观察到的半衰弱和中性$ B $ Meson衰变。我们概括了当前的实验情况。假设当前与SM的紧张局势超出了标准模型来源，我们对有效理论耦合的影响表示了含义。然后，我们讨论一般的leptoquark模型，然后最终将两个标量leptoquarks（$ r_2 $和$ s_3 $）重点放在模型上，这些标量leptoquarks（$ r_2 $ and $ s_3 $）具有由基本的大统一理论框架连接的耦合。我们介绍了模型在Lepton风味普遍性方面的生存能力，并提供了在未来的高强度和高能实验中搜索该模型的机会
We discuss the current status of lepton flavour universality observables in semileptonic charged and neutral current $B$ meson decays. We recapitulate the current experimental situation. Assuming the current tensions with the SM are of beyond the Standard Model origin we present their implications for the effective theory couplings. Then we discuss general leptoquark models before finally focussing on the model with two scalar leptoquarks ($R_2$ and $S_3$) which have couplings connected by the underlying Grand Unified Theory framework. We present the viability of the model with regard to lepton flavour universality and present opportunities to search for this model in future high-intensity and high-energy experiments
