The universality of the weak force coupling to leptons is one of the fundamental pillars of the Standard Model of particle physics. The recent evidence of the breakdown of this principle, which if confirmed would be a ground-breaking discovery, demands further measurements to establish the origin of this effect. This project will deliver the first full angular analysis of b-hadron decays to a charm hadron, a neutrino and either a muon or a tau lepton at LHCb. This measurement has the sensitivity to establish the lepton universality violation effect and investigate the nature of potential New Physics processes.

弱力耦合到轻子的普适性是粒子物理标准模型的基本支柱之一。最近的证据表明，这一原则的崩溃，如果得到证实，将是一个突破性的发现，需要进一步的测量，以确定这种效应的起源。这个项目将提供第一个完整的角度分析b-强子衰变到粲强子，中微子和μ子或τ轻子在LHCb。这种测量对于建立轻子普适性破坏效应和研究潜在的新物理过程的性质具有灵敏度。
