Lepton Flavour Universality (LFU) is a pillar of the Standard Model (SM) that implies equal interaction strength for particles from different lepton families, as the electron and the muon. Several recent experimental results in particle physics seem to suggest possible LFU violation, which is predicted by many Beyond the Standard Model (BSM) scenarios. Kaons, the lightest particles containing the "strange" quark, provide an outstanding way of searching for BSM physics via precise measurements. Experimental studies of decays of strange and light quarks is a very active field of research, and significant progress is expected over the next decade. The NA62 experiment at CERN, a multi-purpose experiment investigating rare kaon decays, is the flagship of the European kaon physics programme and a leader in this field worldwide. NA62 has been operational since 2016 and will continue to collect data at least until 2025. Due to a uniquely intense kaon beam provided by the CERN accelerator complex and a range of state-of-the-art detectors, a variety of stringent SM tests can be performed within the NA62 experiment. In particular, the analysis of leptonic kaon decays within NA62 could lead to the most-precise LFU test in the world. Jamimah will join the NA62 collaboration and will contribute to the LFU research with the NA62 data. An extension of the LFU analysis to constrain several BSM scenarios will be performed. Joining a medium-size international collaboration, Jamimah will have the opportunity to play a leading role on a hot topic in particle physics, while developing key expertise on hardware, software, and data analysis. Jamimah will also spend some months on-site at CERN, acting as a detector expert and doing data-taking shifts.

Lepton风味普遍性（LFU）是标准模型（SM）的支柱，暗示着来自不同Lepton家族的颗粒的相互作用强度，例如电子和MUON。粒子物理学的最新实验结果似乎表明可能违反LFU，这是许多超出标准模型（BSM）场景的预测。 Kaons是包含“奇怪”夸克的最轻的颗粒，它通过精确的测量为搜索BSM物理学提供了出色的方法。奇怪和轻夸克腐烂的实验研究是一个非常活跃的研究领域，预计未来十年将取得重大进展。 CERN的NA62实验是一项多功能实验，调查了稀有Kaon衰减，是欧洲Kaon物理计划的旗舰，也是该领域的领导者。 NA62自2016年以来一直在运行，并将至少在2025年之前继续收集数据。由于CERN Accelerator复合物提供了独特的kaon光束，并且可以在NA62实验中执行各种严格的SM测试。特别是，对Na62内的Leptonic Kaon衰变的分析可能会导致世界上最专业的LFU测试。 Jamimah将加入NA62合作，并将通过NA62数据为LFU研究做出贡献。将执行LFU分析的扩展，以限制几个BSM方案。加入中型国际合作，贾米马（Jamimah）将有机会在粒子物理学中的热门话题上发挥主导作用，同时在硬件，软件和数据分析上开发关键的专业知识。 Jamimah还将在CERN上花费几个月的时间，充当探测器专家并进行数据收集转变。
