Title: 矢量介子产生和核子共振在吉森耦合通道模型中的分析

Abstract: We present a nucleon resonance analysis by simultaneously considering all pion- and photon-induced experimental data on the final states $\gamma N$, $\pi N$, $2\pi N$, $\eta N$, $K\Lambda$, $K\Sigma$, and $\omega N$ for energies from the nucleon mass up to $\sqrt s = 2$ GeV. In this analysis we find strong evidence for various higher lying resonances as, e.g., the $P_{13}(1900)$. The $\omega N$ production mechanism is dominated by large $P_{11}(1710)$ and $P_{13}(1900)$ contributions. Show Chinese abstract

Abstract: 我们通过同时考虑从核子质量到$\sqrt s = 2$GeV 能量范围内的所有介子和光子诱导的最终态$\gamma N$,$\pi N$,$2\pi N$,$\eta N$,$K\Lambda$,$K\Sigma$和$\omega N$的实验数据，进行核子共振分析。 在本分析中，我们发现有强烈证据表明存在各种高能态共振，例如$P_{13}(1900)$。 $\omega N$的产生机制主要由大的$P_{11}(1710)$和$P_{13}(1900)$贡献主导。
