论文摘要
在低能量和高能量下，电子和风味可观察物的精确度量是高度互补的，可以直接搜索高能量乘客的新物理。尽管在大型强子对撞机上发现了希格斯玻色子以及标准模型的压倒性成功，但仍有一些观察和理论问题仍有待解决。除了中微子振荡现象外，标准模型还无法解释宇宙的重子不对称性，也没有提供可行的暗物质候选者。近年来，已经确定了标准模型预测与实验测量之间的许多偏差。有趣的是，大多数人与Lepton的口味紧密相关。 在本论文中，我们探讨了风味物理学的几个方面，重点是大规模中微子模型的现象学含义，以及能够在带电的lept子的异常磁矩和几个$ b $ b $ - $ - $ - 米斯森衰减的观察值的几种标准模型扩展中。
Precision measures of electroweak and flavour observables, at both low and high energies, are highly complementary to direct searches for New Physics at high-energy colliders. Despite the discovery of the Higgs boson at the Large Hadron Collider, and of the overwhelming successes of the Standard Model, several observational and theoretical problems remain to be addressed. In addition to neutrino oscillation phenomena, the Standard Model fails to explain the baryon asymmetry of the Universe, and does not offer a viable dark matter candidate. In recent years, numerous deviations between the Standard Model prediction and experimental measurements have been identified; interestingly, most are closely connected to lepton flavours. In this thesis we have explored several aspects of flavour physics, focusing on the phenomenological implications of models of massive neutrinos, and of several Standard Model extensions capable of accommodating current tensions on anomalous magnetic moments of charged leptons and several $B$-meson decay observables.
