Abstract

Neutrons produced during scattering of muon antineutrinos through charged currents in the ND280 near neutrino detector of the T2K experiment are studied. Based on Monte-Carlo simulations of the beam of accelerator antineutrinos with an energy of ~0.6 GeV, the kinematics of the quasi-elastic interaction is reconstructed. Energy and angular distributions of neutrons are obtained, their detection efficiency is calculated using a method accounting for the particle time of flight.

T2K实验中微子探测器附近的ND280中的Muon反中微子相互作用产生的中子的研究

摘要

研究了在T2K实验的中微子探测器附近的ND280中通过带电电流在μ子抗中微子的散射过程中产生的中子。基于能量约为0.6 GeV的加速器反中微子束的蒙特卡洛模拟，重建了准弹性相互作用的运动学。获得了中子的能量和角分布，使用考虑了粒子飞行时间的方法计算了它们的检测效率。
