寻找中子镜中子振荡的超冷中子实验的蒙特卡罗模拟
Monte Carlo simulation for Ultra-cold neutron experiments searching for neutron - mirror neutron oscillation
摘要：
中子振荡成镜像中子，一种与中子质量完全简并的无菌状态，可能是一个非常快的过程，甚至比中子衰变本身还要快。通过比较不同实验磁场下超冷中子俘获实验中的中子损失率，可以观察到这一现象。我们开发了一个Monte Carlo代码，它模拟了这种具有非均匀磁场的实验的许多特征。模拟的目的是提供所有必要的工具，需要分析不同几何形状和不同配置的磁场的中子阱的实验结果。本工作包含用于arXiv：1712.05761中分析的蒙特卡罗模拟的技术细节。
英文摘要：
Neutron oscillation into mirror neutron, a sterile state exactly degenerate in mass with the neutron, could be a very rapid process, even faster than the neutron decay itself. It can be observed by comparing the neutron lose rates in an ultra-cold neutron trapping experiment for different experimental magnetic fields. We developed a Monte Carlo code that simulates many of the features of this kind of experiment with non-uniform magnetic fields. The aim of the simulation is to provide all necessary tools, needed for analyzing experimental results for neutron traps with different geometry and different configurations of magnetic field. This work contain technical details on the Monte Carlo simulation used for the analysis in arXiv:1712.05761 not presented in it.
