Next generation neutrino experiments such as Hyper-Kamiokande require neutrino interaction cross-section uncertainties to be reduced to the few-percent level if a competitive constraint is to be placed on the magnitude of CP violation in the neutrino sector. One major challenge in reducing these uncertainties is that 'final state interactions', interactions between outgoing nucleons and pions as they leave nuclei, can shield our view of the primary neutrino interaction vertex. In this project Tom will explore how new constraints could be placed on final state interactions using pion and nucleon scattering data from thick target experiments, before exploring how these new constraints could improve neutrino oscillation analyses on the Tokai-to-Kamiokande experiment and future Hyper-Kamiokande experiment.

下微中微子实验（例如Hyper-Kamiokande）需要中微子相互作用的横截面不确定性，如果将竞争性约束放在中微子部门的CP违规幅度上，则需要将中微子相互作用的横截面不确定性降低到几％。减少这些不确定性的一个主要挑战是“最终状态相互作用”，即传出的核子和胎胎在离开核时之间的相互作用，可以掩盖我们对主要中微子相互作用顶点的看法。在这个项目中，汤姆将探索如何使用厚度目标实验的锥形和核子散射数据对最终状态相互作用进行新的约束，然后再探索这些新约束如何改善对Tokai-to-Kamiokande实验和未来Hyper-Kamiokande实验的中微子振荡分析。
