Description
The ANL-Osaka coupled-channel model of $\pi N$ and $\gamma N$ reactions is developed to investigate the nucleon resonances up to 2GeV.
We briefly explain the coupled channel reaction formula including stable meson-baryon ($\pi N, \eta N, K \Lambda, K\Sigma$) channels, unstable meson-baryon($\pi\Delta,\rho N,\sigma N$) channels and $\pi\pi N$, and the analysis of pion-, photon- and electron-induced reactions. Parameters of nucleon resonances and the interpretation of their structure within the model is discussed.
Extension of the model for the $\bar{K}N$ reaction, neutrino reaction and our recent efforts for the analysis of the hadron reactions will be briefly discussed.
