我们提出了一种新的蒙特卡罗 μ 介子传播算法 MUM (MUons+Medium)，它比目前使用的类似算法具有一些优势。描述了算法最重要的特征。介绍并分析了用 MUM 处理 μ 子能量损失的准确性的测试结果。根据模拟参数，其评估结果为 0.002 或更好。考虑并排序了蒙特卡罗μ介子传输中应用的不同简化对所得误差的贡献。结果表明，当模拟介子在介质中传播时，仅考虑辐射能量损失的波动就足够了，能量损失的比例高达 0.05 - 0.1。给出了使用 MUM 获得的选定结果，并将其与其他算法的结果进行了比较。
We present a new Monte Carlo muon propagation algorithm MUM (MUons+Medium) which possesses some advantages over analogous algorithms presently in use. The most important features of algorithm are described. Results on the test for accuracy of treatment the muon energy loss with MUM are presented and analyzed. It is evaluated to be of 0.002 or better, depending upon simulation parameters. Contributions of different simplifications which are applied at Monte Carlo muon transportation to the resulting error are considered and ranked. It is shown that when simulating muon propagation through medium it is quite enough to account only for fluctuations in radiative energy loss with fraction of energy lost being as large as 0.05 -- 0.1. Selected results obtained with MUM are given and compared with ones from other algorithms.
