摘要
对L3宇宙线实验中 μ子事例的动量重建方法进行了研究 .在事例的重建中 ,考虑了某些影响径迹重建精度的因素 ,如磁谱仪内部磁场的非均匀性和仪器自身物质对粒子的多次散射等过程引起的误差 .经过修正后的 μ子事例的动量分辨有了显著的改善 .
The reconstruction method of muon tracks in the L3 Cosmic Ray Experiment has been studied.The affection caused by the non-uniformity of magnetic field,multiple scattering and other random processes have been investigated by the Geane package.After correction,the momentum resolution of the reconstructed muons was improved.
