Calculation of the Cherenkov light yield from low energetic secondary particles accompanying high-energy muons in ice and water with Geant 4 simulations
摘要：
在这项工作中，我们调查和参数化的切伦科夫光子，这是由低能量的二次粒子（通常$\lesssim 500 $ \，兆电子伏），伴随着μ子在水或冰的轨道产生的量和角分布。这些次级粒子来自小能量损失过程。我们调查的贡献不同的能量损失过程的μ子能量和最大转移能量的函数。对于角分布的计算，我们已经开发了一个通用的变换方法，它使我们能够导出的角分布的Cherenkov光子的轨道方向和它们的速度的任意分布。
英文摘要：
In this work we investigate and parameterize the amount and angular distribution of Cherenkov photons, which are generated by low-energy secondary particles (typically $\lesssim 500 $\,MeV), which accompany a muon track in water or ice. These secondary particles originate from small energy loss processes. We investigate the contributions of the different energy loss processes as a function of the muon energy and the maximum transferred energy. For the calculation of the angular distribution we have developed a generic transformation method, which allows us to derive the angular distribution of Cherenkov photons for an arbitrary distribution of track directions and their velocities.
