摘要

近距离探测器ND280是T2K实验的重要组成部分。它的数据被用来调整截面和通量模型的参数，从而减少了系统的不确定性，提高了中微子振荡测量的精度。ND280是一种由几个子探测器组成的复杂装置。这种结构导致了与中微子相互作用产物的模拟和跟踪有关的各种系统不确定性的来源。本文介绍了估计系统误差的方法，并将其通过各阶段传播到最后的振荡分析。

Estimation of Systematic Uncertainties for the Data Analysis in the Near Detector of the T2K Neutrino Experiment

The near detector ND280 is an essential part of the T2K experiment. Its data are used to tune the parameters of the cross-section and flux models, thereby reducing systematic uncertainties and enhancing the precision of neutrino oscillation measurements. ND280 is a complex apparatus consisting of several subdetectors. The structure leads to various sources of systematic uncertainties related to the simulation and tracking of neutrino interaction products. This paper presents the methods used to estimate the systematic errors and to propagate them through the stages towards the final oscillation analysis.
