Various deviations in the B-meson sector from the Standard Model predictions can potentially be explained by so-called leptoquarks. These are particles which couple simultaneously to lepton and quarks. Moreover, with the help of these particles one could in principle also explain a potential resonance in the di-photon spectrum close to 750 GeV which has been observed by the LHC collaborations ATLAS and CMS. In this project we will investigate to which extent different models are consistent with the combination of data from precision observables, flavour physics and high energy colliders like the LHC. In addition we will work out predictions of these models for the LHC.

B 介子区域与标准模型预测的各种偏差可以用所谓的轻夸克来解释。这些粒子同时与轻子和夸克耦合。此外，借助这些粒子，原则上还可以解释接近 750 GeV 的双光子光谱中的潜在共振，大型强子对撞机合作组织 ATLAS 和 CMS 已观察到这一现象。在这个项目中，我们将研究不同模型在多大程度上与来自精密观测、风味物理学和大型强子对撞机等高能对撞机的数据组合一致。此外，我们还将对大型强子对撞机的这些模型进行预测。
