Fast reconstruction algorithm in main drift chamber for the BESIII event filter(北京谱仪Ⅲ事例筛选的主漂移室快速重建算法实现) by CHENXiao-feng(陈晓峰), DAIYou-shan(戴又善), YUGuo-wei(俞国威)

“…陈述了在北京正负电子对撞机重大升级改造工程(BEPCⅡ )中一个应用于北京谱仪Ⅲ (BESⅢ)主漂移室(MDC)事例筛选的快速重建算法.为了实现此算法并保证算法的可扩展性，利用C++编写了 MdcLutHough模式识别程序并展示出应用此程序进行径迹识别的效果，其径迹拟合的效率大约为95%，粒子横动量PT的分辨率则小于5% .该快速重建算法将在BESⅢ的计算机数据重建中发挥其应用价值.…”
