摘要
为在当前及未来使用氩探测器的实验中利用GeV能量中微子束探测轻子 sector 的CP破坏,需要复杂底层中微子与反中微子相互作用的精确模型。Jefferson实验室A厅的E12-14-012实验旨在利用GeV能量电子束对氩()与钛()核进行包含与排他电子散射的联合分析。对钛核的测量为理解氩上中微子散射提供必要信息,后者很大贡献来自中子散射。本文报道首个电子-钛散射实验研究,即束流能量 GeV、电子散射角 deg下的双微分截面,测量覆盖宽能量转移范围,跨越准弹性散射与delta产生为主导反应机制的运动学区域。数据为开发这些复杂核的电磁与弱截面精确理论模型提供了有价值的新信息,该运动学区间正是中微子实验所关注的。
