Nucleon decay search and cosmic rays in the DUNE experiment

深层地下中微子实验(DUNE)将对中微子振荡进行精确测量，并在标准模型之外寻找粒子物理中的其他效应，如核子衰变。这项拟议中的研究重点是寻找核子衰变，这是现代物理学中一个令人兴奋的话题。该项目涉及开发先进的方法，将潜在的核子衰变事件与宇宙射线µ子引起的背景区分开来。我们计划改进事件重建和粒子识别的算法，并应用机器学习技术来提高识别信号事件和剔除宇宙线背景的效率。我们将使用模拟数据，以及ProtoDUNE和SBND等原型实验收集的数据。英国(谢菲尔德)物理学家和马来西亚科学家之间的合作将使马来西亚的学者和博士生能够接受粒子物理、数据密集型科学和应用于复杂粒子物理问题的机器学习技术领域的培训。

The Deep Underground Neutrino experiment (DUNE) will carry out accurate measurements of neutrino oscillations and search for other effects in particle physics beyond the Standard model, such as nucleon decay. The proposed research focuses on a search for nucleon decay as an exciting topic in modern physics. The project involves development of advanced methods for discriminating potential nucleon decay events from a background caused by cosmic-ray muons. We plan to improve on algorithms for event reconstruction and particle identification and apply machine learning techniques to increase the efficiency of identifying signal events and rejecting cosmic-ray background. We will be working with simulated data, as well as the data collected by prototype experiments, such as ProtoDUNE and SBND. Working in collaboration between UK (Sheffield) physicists and Malaysian scientists will allow academics and PhD students from Malaysia to be trained in the areas of particle physics, data intensive science and machine learning techniques applied to complex particle physics problems.
