项目摘要

Particle physics is concerned with the study of the fundamental particles of nature and the interactions between them. By understanding how these particles interact, insight will be gained about the origin of the Universe. To study these particles and their behaviour highly specialised detectors and equipment must be used. One such example is the Tokai to Kamioka (T2K) neutrino oscillation experiment, based in Japan. In 2011 the T2K experiment reported evidence indicating that the third neutrino mixing angle was non-zero. With additional data in 2013, T2K confirmed electron neutrino appearance in a muon neutrino beam which provides the possibility of CP-violation in the neutrino sector of the Standard Model. I will continue to work with the T2K experiment and will focus on the measurement of Neutral Current cross-sections using data from the near detector. Such measurements are important for current and future neutrino oscillation experiments. Future long baseline experiments are planned to investigate and quantify delta, the parameter associated with CP-violation. If delta is found to be non-zero, it could help explain the matter-antimatter asymmetry of the Universe. I am currently involved with the design and optimisation of data acquisition systems for the planned HyperKamiokande experiment. Such systems will be important for HyperKamiokande and other future neutrino experiments.

粒子物理学研究自然界的基本粒子和它们之间的相互作用。通过了解这些粒子是如何相互作用的，我们将对宇宙的起源有所了解。为了研究这些粒子及其行为，必须使用高度专业化的探测器和设备。其中一个例子是日本的东海到神冈（T2K）中微子振荡实验。2011年，T2K实验报告了第三个中微子混合角非零的证据。在2013年的额外数据中，T2K证实了电子中微子出现在μ子中微子束中，这为标准模型的中微子部分提供了cp违反的可能性。我将继续进行T2K实验，并将重点放在使用近探测器的数据测量中性电流横截面上。这些测量对于当前和未来的中微子振荡实验都很重要。未来的长基线实验计划研究和量化delta，这是与cp违反相关的参数。如果发现delta不为零，它将有助于解释宇宙中物质与反物质的不对称性。我目前参与了计划中的超级神冈实验的数据采集系统的设计和优化。这样的系统对于超级神冈和其他未来的中微子实验将是重要的。
