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

最近的测量暗示了轻子普适性的瓦解，而普适性是粒子物理学标准模型的核心原则。在LHCb中同时分析b强子衰变为粲强子、中微子和μ子或tau轻子，具有建立效应和研究潜在新物理过程性质的灵敏度，当包括cp违反和角度观测时。出色的轨道重建能力对未来升级的LHCb物理计划至关重要。在这个项目中，新的轨道重建策略将找到与使用新兴技术的探测器的最佳匹配，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.
