The nucleon resonances are investigated within a dynamical coupled-channels model of $\ensuremath{\pi}N$ and $\ensuremath{\gamma}N$ reactions up to the invariant mass $W=2$ GeV. The meson-baryon ($MB$) channels included in the calculations are $MB=$ $\ensuremath{\pi}N$, $\ensuremath{\eta}N$, $K\ensuremath{\Lambda}$, $K\ensuremath{\Sigma}$, and $\ensuremath{\pi}\ensuremath{\pi}N$ that has $\ensuremath{\pi}\ensuremath{\Delta}$, $\ensuremath{\rho}N$, and $\ensuremath{\sigma}N$ resonant components. The meson-baryon amplitudes ${T}_{{M}^{\ensuremath{'}}{B}^{\ensuremath{'}},MB}(W)$ …
