我们考虑了最近的两个π−p→ηn测量对ηN弹性散射和ηN产生数据的耦合通道分析中N(15 35)和N(15 2 0)共振的πN散射长度和ηN分支分数的影响。文中还探讨了这些结果对模型输入的敏感性。
We consider the impact of two recent π − p → ηn measurements on the ηN scattering length and ηN branching fractions for the N (1535) and N (1520) resonances within a coupled-channel analysis of πN elastic scattering and ηN production data. The sensitivity of these results to model input is also explored.
