The aim of the proposed research is to further understand our Universe at its most basic level via the study of elementary particles and their interactions. Gaining further insight into the properties of the basic building blocks of the Universe (elementary particles) and the nature of the fundamental forces which govern the interactions of these particles will permit deep insights into the origin and evolution of the Universe, especially in the first moments after the Big Bang. The Lancaster Experimental Particle Physics group is involved with a number of experiments at the Large Hadron Collider (LHC) at CERN that are designed to test our understanding of these fundamental particles and forces (the Standard Model) and also undertake searches for new particles and new physics. The group is also involved in experiments that study neutrinos (one specific type of fundamental particle), searches for Dark Matter candidates and detector development. This proposal focuses on a sub-set of the group's activities within the ATLAS, NA62 and T2K experiments. Using data accumulated by the ATLAS experiment at the LHC, we will study the nature of the Higgs boson and search for anomalies in the Standard Model via studies of heavy quark decays. Searches for di-Higgs production will allow deeper understanding of its role in the universe, nature and properties, providing important information . Studies of heavy quark decays will investigate lepton flavour universality, i.e. whether the different types of leptons couple to the W boson with equal strength. Lepton flavour universality is not associated with any known symmetry and its origins are not known. This is therefore a very interesting area of investigation. The NA62 experiment offers a unique opportunity to explore the precision frontier of the Standard Model (SM) in a complementary and synergistic way to the LHC experiments. NA62 will execute stringent tests of the Standard Model, search for ultra-rare processes and undertake studies of lepton flavour universality. This work will probe our understanding of fundamental particles and their interactions to an unprecedented level. By developing new selections for particles produced in neutrino interactions at the T2K experiment, improved understanding of neutrino interactions models can be gained. This will lead to improved measurements of neutrino oscillations with the T2K experiment and provide important information for next-generation experiments that are planned to establish the existence of CP violation in the neutrino sector of the Standard Model. This could have wide reaching implications for the understanding of the matter- antimatter asymmetry of the Universe.

拟议研究的目的是通过研究基本颗粒及其相互作用来进一步了解我们的宇宙。进一步了解宇宙基本构建块（基本粒子）的性质以及控制这些粒子相互作用的基本力的性质，将允许深入了解宇宙的起源和演变，尤其是在大爆炸之后的第一刻。兰开斯特实​​验粒子物理组与CERN的大型强子对撞机（LHC）的许多实验有关，这些实验旨在测试我们对这些基本颗粒和力的理解（标准模型），还进行了对新颗粒和新物理学的搜索。该小组还参与了研究中微子（一种特定类型的基本粒子），寻找候选暗物质和探测器发展的实验。该提案重点介绍了该集团在Atlas，Na62和T2K实验中的活动的子集。利用LHC Atlas实验累积的数据，我们将通过重夸克腐烂的研究来研究Higgs玻色子的性质，并在标准模型中搜索标准模型中的异常。搜索Di-higgs生产将使人们更深入地了解其在宇宙，自然和属性中的作用，从而提供重要信息。对夸克衰减的研究将研究Lepton风味的普遍性，即不同类型的Leptons夫妇是否具有相同的强度到W玻色子。 Lepton风味普遍性与任何已知的对称性无关，其起源尚不清楚。因此，这是一个非常有趣的调查领域。 NA62实验提供了一个独特的机会，可以通过与LHC实验的互补和协同方式探索标准模型（SM）的精确边界。 NA62将对标准模型进行严格的测试，寻找超稀有过程，并对Lepton风味普遍性进行研究。这项工作将探究我们对基本粒子及其相互作用的理解，直到前所未有的水平。通过在T2K实验中为中微子相互作用中产生的颗粒开发新的选择，可以提高对中微子相互作用模型的了解。这将通过T2K实验改进中微子振荡的测量结果，并为下一代实验提供重要信息，这些实验计划在标准模型的中微子部门中确定CP违规存在。这可能对理解宇宙的物质不对称性具有广泛的影响。
