摘要
利用费米实验室 NuMI 宽能谱中微子束照射下的 MINERvA 探测器，研究了塑料（CH）上通过带电流 相互作用产生的带电π介子。选取强子不变质量 W 1.4 GeV 的事例以隔离单π介子产生过程，该过程预计主要通过 共振发生。报告了作为π介子产生角和动能函数的截面，并将其与能量范围从 1.5 GeV 到 10 GeV 的中微子的不同理论计算和基于发生器（generator-based）模型的预测进行了比较。数据最符合那些包含显著π介子核内再散射（intranuclear rescattering）贡献的计算结果。这些测量限制了初级相互作用速率以及末态相互作用在π介子产生中的作用，这两者都需要被中微子振荡实验充分理解。
