用近场探测器ND280研究T2K中微子束中的本征电子中微子成分

Study of the intrinsic electron neutrino component in the T2K neutrino beam with the near detector, ND280

Sophie E. King

摘要:

T2 K是一个离轴长基线中微子振荡实验,优化使用μ子中微子束测量θ 13和δ CP。最灵敏的模式是寻找电子中微子的出现,而这种测量的主要背景是束流本身的固有电子中微子成分。使用离轴近探测器(ND 280)的数据进行选择,以检测带电电流(CC)电子中微子相互作用;这些被分成最终状态中没有π介子的事件(nue CC 0 pi)和剩余的CC相互作用(nue CCother)。该策略将通过该分析改进固有背景的约束,并且允许测量CC 0 pi截面

英文摘要:

T2K is an off-axis long baseline neutrino oscillation experiment optimised to measure theta13 and deltaCP using a muon neutrino beam. The most sensitive mode is to look for electron neutrino appearance, and the dominant background for such measurements is the intrinsic electron neutrino component in the beam itself. A selection is made using data from the off-axis near detector (ND280) to detect charged current (CC) electron neutrino interactions; these are split into events with no pions in the final state (nue CC0pi) and the remaining CC interactions (nue CCother). This strategy will both improve the constraint of the intrinsic background by this analysis and allow a measurement of the CC0pi cross section
