η'衰变到γπ^+π^-的蒙特卡罗产生子研究

Event Generators for η' Decays into γπ^+π^-

在高能物理实验数据分析中,事例选择效率是排除探测器和数据分析因素,从而获得物理测量量的必要输入参量.蒙特卡罗(MC)模拟是获得事例选择效率的唯一方法.结合实验数据与现有的理论模型,研究考虑了盒子反常效应的η'衰变到γπ+π-蒙特卡罗产生子的方法,获得的结果能够较好地与实验数据符合.

In high energy physics experiments of data analysis, the efficiency of event selection is an important parameter in the measurement of physical analysis, event selection efficiency can also exclude the impact of the detector and data analysis. Monte Carlo simulation is the only way to obtain selection efficiency. In this paper, we study the Monte Carlo event generator of decay to taking into account the box anomaly effect, while combining the experimental data with the existing theoretical models.
