摘要
我们报告了MicroBooNE首次搜索暗区 解释长期存在的MiniBooNE异常. MiniBooNE异常在过去20年间引起广泛关注，包括之前的MicroBooNE针对异常电子和光子过量的调查，但其起源仍不明. 本文提供首次对暗区模型的直接测试，这些模型中暗色子通过 neutrino 诱导散射产生，衰变为缺失能量和可见 对，构成MiniBooNE异常. 许多此类模型最近因能提供该异常解决方案而受到青睐，同时规避了过去的限制. 使用 目标质子的暴露量，我们实施针对正向产生、共振产生的 事件的选择. 在解除封锁后，我们观察到95个事件，将其与受约束的背景-only预测 进行比较. 本分析设定了世界首个针对这些暗区模型的直接限制，并在95%置信水平下排除了大多数作为MiniBooNE异常解决方案而可行的参数空间.
