Coupled channel dynamics (B11)

尽管从各种π介子、光子和电子诱导的反应中可以获得许多关于重子共振的高质量数据，但我们仍然远离一个完整和明确的重子共振谱图。因此，开发可靠的工具将理论预测与现有的实验数据联系起来至关重要。当从观测量中提取中等能量区的重子共振谱时，由于几个非弹性通道的开放，耦合通道动力学起着至关重要的作用。耦合通道方法将不同的反应通道和分波联系起来，可以同时分析具有不同初始和最终状态的多个反应。在此期间，我们希望进一步改进Jülich-Bonn动力学耦合通道模型来研究矢量介子产生，KN反应来研究超子共振，包括中子和电产生反应的光生过程，并使用扩展的动力学耦合通道方法来提供除了LHCb实验新观察到的三个外的完整的Pc态谱。

Despite the many high quality data on baryon resonances that are available from a variety of pion-, photon- and electron-induced reactions, we are still far away from a complete and unambiguous picture of the baryon resonance spectrum. Therefore, the development of reliable tools to connect theoretical predictions to the available experimental data is essential. When extracting the spectrum of baryon resonances in the medium energy regime from observables, coupled-channel dynamics play a crucial role due to the opening of several inelastic channels. Coupled-channel approaches link the different reaction channels and partial waves and allow for a simultaneous analysis of multiple reactions with different initial and final states. In this period, we want to further refine the Jülich-Bonn dynamical coupled-channel model to study vector meson production, KN reactions to study hyperon resonances, include photoproduction processes on the neutron and electroproduction reactions and also use an extended dynamical coupled-channels approach to provide a complete spectrum of Pc states in addition to the three newly observed ones by LHCb experiment.
