摘要

标准模型(SM)的电弱规范玻色子与轻子的耦合是普遍存在的。SM的扩展不一定具有这个性质。重味的罕见衰变在SM中被抑制，新粒子可能对这些过程有相当大的贡献，因此，它们的精确研究允许对轻子味普遍性的敏感测试。特别令人感兴趣的是在LHCb实验中很容易获得的罕见的b→sl+l−衰变。讨论了LHCb在罕见的b→sl+l−衰变中关于轻子味普遍性的最新结果。

Lepton Flavour Universality tests in electroweak penguin decays at LHCb

The coupling of the electroweak gauge bosons of the Standard Model (SM) to leptons is flavour universal. Extensions of the SM do not necessarily have this property. Rare decays of heavy flavour are suppressed in the SM and new particles may give sizeable contributions to these processes, therefore, their precise study allows for sensitive tests of lepton flavour universality. Of particular interest are rare b→ sl+l− decays that are well accessible at the LHCb experiment. Recent results from LHCb on lepton flavour universality in rare b→ sl+l− decays are discussed.
