分析了MAMI A2协作组提供的数据，以逐个事件地选择反应，与测量分布拟合相比，这允许对三体最终状态进行分波分析，以获得更可靠的结果。这些数据在从阈值到GeV的能量范围内提供了世界上最好的统计精度，允许在理解反应动力学所需的所有可观测量的测量中进行更精细的能量分级。测量的可观测量得到的结果进行比较，现有的模型，并检查新数据的影响与修订后的美因茨模型的拟合。
The data available from the A2 Collaboration at MAMI were analyzed to select thereaction on an event-by-event basis, which allows for partial-wave analyses of three-body final states to obtain more reliable results, compared to fits to measured distributions. These data provide the world's best statistical accuracy in the energy range from threshold toGeV, allowing a finer energy binning in the measurement of all observables needed for understanding the reaction dynamics. The results obtained for the measured observables are compared to existing models, and the impact from the new data is checked by the fit with the revised Mainz model.
