摘要
我们报告了首次同时针对含质子与不含质子末态的双微分中微子-氩截面测量，涉及包含性缪子中微子带电流相互作用通道。通过测量领头质子动能（跨越探测阈值）的微分截面，进一步探索了该通道的质子运动学。这些测量利用了MicroBooNE探测器收集的数据，来自费米实验室助推器中微子束的6.4×10^20个质子打靶，平均中微子能量约为0.8 GeV。采用了基于条件约束形式的数据驱动模型验证方法。这促使通过经验重加权方法扩大不确定性，以最小化提取有偏截面结果的可能性。将提取的名义通量平均截面与广泛使用的事件生成器预测进行比较，揭示了缪子中微子带电流相互作用中不含质子末态的严重模型错误，可能源于对末态相互作用的处理不足。这些测量提供了丰富的新信息，有助于改进事件生成器，从而增强中微子实验精密测量的灵敏度。
