New Physics searches using semi-leptonic b-hadron decays at LHCb

最近的测量已经暗示了轻子普适性的崩溃，轻子普适性是粒子物理学标准模型的核心原理。在LHCb上同时分析b强子衰变为粲强子、中微子和μ介子或τ轻子的过程，对于建立这种效应和研究潜在的新物理过程的性质具有灵敏度，同时考虑到CP破坏和角向观测量，良好的径迹重建能力对于LHCb未来的物理升级计划是必不可少的。在该项目中，新的轨道重建策略将使用新兴技术找到与检测器的最佳匹配，以满足具有挑战性的数据采集条件下的性能要求。

Recent measurements have hinted to the breakdown of lepton universality, a central principle of the Standard Model of particle physics. The simultaneous analysis of b-hadron decays to a charm hadron, a neutrino and either a muon or a tau lepton at LHCb has the sensitivity to establish the effect and investigate the nature of potential New Physics processes, when including CP-violating and angular observables.Excellent track reconstruction capabilities are essential for the physics programme of LHCb future upgrades. In this project new track reconstruction strategies will find the best match with detectors using emerging technologies, to meet the performance requirements in challenging data taking conditions.
