论文摘要
我们通过Hamiltonian有效的理论分析了负奇迹通道中的$γn\toπn$过程，该理论成功地研究了与介子 - 核子散射和晶格QCD模拟相关的核子共振。我们提供锥形光生源的散射幅度，并提取电偶极振幅$ e_ {0+} $。 $ n^*（1535）$中的Triquark组件对于改善我们的结果与实验数据之间的一致性很重要。
We analyze the $γN\toπN$ process in the negative parity channel with Hamiltonian effective filed theory which is successful in studying the nucleon resonances associated with the meson-nucleon scattering and lattice QCD simulations. We provide the scattering amplitude of pion photoproduction and extract the electric dipole amplitudes $E_{0+}$. The triquark component in $N^*(1535)$ is important for improving the consistence between our results and the experimental data.
