Study of neutrino ineractions using the WAGASCI detector in the T2K experiment

该研究员的第一项任务是为T2K实验的WAGASCI近探测器开发软件。这涉及到在以前的维护人员离开T2K协作时获得软件项目的所有权，并确保以一致的方式将最新的更改纳入代码。他还对与该项目相关的所有代码包进行了对比，以确保代码能够跨平台工作，并能够在世界各地的不同计算集群上运行。下一个相关任务是MC生产，其中涉及运行模拟探测器中完整事件链所需的所有代码。在第一步中实现的代码的组织和容器化极大地帮助了这项任务，并提供了新的模拟样本，可用于未来的研究。他编写了文档，分发给所有合作者，说明如何实现这项任务，确保这种机构知识将在实验中得到保留。该研究员开发了一种新的选择，利用数据进行新的联合横截面分析ND280和WAGASCI近距离探测器。这将是第一次使用这些探测器进行联合分析，其灵敏度将高于任何一个单独探测器所能达到的灵敏度。这涉及开发新的软件工具，对两个探测器数据集进行数据分析，并将作为进一步联合分析的途径，具有未来的价值。

The first task of the fellow was working on the software for the WAGASCI near detector for the T2K experiment. This involved taking ownership of the software project as the previous maintainers had left the T2K collaboration and ensuring that the latest changes were incorporated into the code in a consistent manner. He also conainterised all code packages associated with this project to ensure that the code worked across platforms and could be run at different computing clusters around the world.The next related task was MC production which involved running all of the code required to simulate the full chain of events in the detector. The organisation and containerisation of the code achieved in the first step greatly aided this task and provided new simulation samples that can be used in future studies.He wrote documentation which was distributed to all collaborators on how this task can be achieved, ensuring that this institutional knowledge will be preserved within the experiment.The fellow developed a new selection with which to perform a new joint cross section analysis using data from both the ND280 and WAGASCI near detectors. This will be the first joint analysis using these detectors and will have a sensitivity greater than that which either individual detector could achieve. This involved developing new software tools to perform data analysis on both detector data sets and will have future value as a path to further joint analyses.The fellow also travelled to JPARC to participate in data taking activity.
