本文对辐射J/psi衰变产生的pi(0)pi(0)系统进行了振幅分析。具体地，描述pi(0)pi(0)系统的动力学的分段函数根据由BES III探测器收集的(1.311+/-0.011)×10(9)J/psi衰变的分析确定为Mpi(0)pi(0)的函数。这个分析的目的是提供对pi(0)pi(0)系统的标量和张量分量的描述，同时对振幅中的极点的性质或数量做出最小的假设。这种与模型无关的描述允许人们将这些结果与现象学模型开发中互补反应的其他相关结果相结合，然后可以用于直接拟合实验数据以获得感兴趣的参数。J/psi->；pi(0)pi(0)的分支分数被确定为(1.15+/-0.05)×10(-3)，其中不确定度仅是系统的，统计不确定度可以忽略不计。
An amplitude analysis of the pi(0)pi(0) system produced in radiative J/psi decays is presented. In particular, a piecewise function that describes the dynamics of the pi(0)pi(0) system is determined as a function of M pi(0)pi(0) from an analysis of the (1.311 +/- 0.011) x 10(9) J/psi decays collected by the BESIII detector. The goal of this analysis is to provide a description of the scalar and tensor components of the pi(0)pi(0) system while making minimal assumptions about the properties or number of poles in the amplitude. Such a model-independent description allows one to integrate these results with other related results from complementary reactions in the development of phenomenological models, which can then be used to directly fit experimental data to obtain parameters of interest. The branching fraction of J/psi -> pi(0)pi(0) is determined to be (1.15 +/- 0.05) x 10(-3), where the uncertainty is systematic only and the statistical uncertainty is negligible.
