论文摘要
在各种标准模型扩展中预测了中子为隐藏扇区粒子的振荡。这种额外的中子消失通道尚未在振荡参数空间的大部分中进行实验测试。最近在超冷中子（UCN）存储实验中修改低质量分解时的振荡时间限制以及在较大的质量分解中进行了几项努力。在这项工作中，我们介绍了一个实验的预期灵敏度，该实验通过在中间质量分解的中子隐藏中子中子振荡搜索磁场$ b_0 = 30-1100 $ $ $ $ $ t。该实验是使用新型的UCN计数器在研究所 - 洛格 - 兰格文（Institut-Laue-Langevin）进行的，以监测梁通量。测得的UCN速率和数据收集技术预测了几秒钟水平的振荡时间的敏感性。
Oscillations of the neutron into a hidden sector particle are processes predicted in various Standard Model extensions. This extra channel for neutron disappearance has not been tested experimentally in large portions of the oscillation parameter space. Several efforts have been recently made on revising the oscillation time limits at low mass-splitting in ultra-cold neutron (UCN) storage experiments, and at larger mass-splitting in passing-through-wall experiments. In this work, we present the expected sensitivity of an experiment searching for neutron hidden neutron oscillations at intermediate mass-splitting via the application of magnetic fields in the range $B_0=30-1100$ $μ$T. This experiment was performed at the Institut-Laue-Langevin using a novel UCN counter to monitor the beam flux. The measured UCN rate and the data collection technique predict a sensitivity on the oscillation time at the level of a couple of seconds.
