Neutrino interactions in the Electromagnetic Calorimeter of the T2K near detector

T2K实验的离轴近探测器ND280包含几种作为中微子相互作用目标的材料。其中最有效的一种是电磁量热计（ECal）中的铅。尽管中微子相互作用截面的测量本身就很重要，而且对于中微子振荡实验中高精度测量的进展至关重要，但迄今为止，铅的截面尚未得到很好的测量。以前T2K的博士生已经开发了测量ECal中铅的中微子相互作用率和横截面的算法。乔将继续这项工作，以生产一个比率和/或横断面出版物的目标。这一测量不仅对T2K有贡献，而且对一般的中微子精确测量领域也有贡献。这个项目也将包含对实验的服务工作。这项工作将涉及ECal事件重建代码的软件开发和维护，Tokai现场的探测器操作员轮班，以及负责ND280子探测器的日常检查和校准的专家探测器轮班。

The off-axis near detector ND280 of the T2K experiment contains several materials that act as targets for neutrino interactions. One of the most efficient of these is the lead in the electromagnetic calorimeter, ECal. Although neutrino interaction cross sections are important to measure in their own right, and in addition are essential for the progress of high-precision measurements in neutrino oscillation experiments, cross sections on lead have not been well measured to date. Previous T2K PhD students have developed algorithms for measuring the neutrino interaction rate and cross section on lead in the ECal. Joe will continue this work with the aim of producing a rate and/or cross-section publication. This measurement will contribute not only to T2K but to the field of neutrino precision measurements in general.This project also will contain an element of service work to the experiment. This work will involve software development and maintenance of the ECal event reconstruction code, detector operator shifts on site in Tokai, and expert detector shifts with responsibility for the day-to-day checks and calibrations of several of the ND280 sub-detectors.
