摘要：

The reactions (gamma/pi) -> gamma N, pi N, 2 pi N, eta N, K Lambda, K Sigma, omega N are simultaneously analysed within a coupled-channel unitary Lagrangian approach (Giessen Model). The resonance contributions to the different transition channels are shown and discussed. The results for eta N and K Lambda final states in both pion- and photo-induced reactions are presented in more details in prospect of new experimental data from MAMI and CLAS. The recent progress in the description of the 2 pi N channel in terms of the pi N -> rho N, sigma N, pi Delta transitions is presented.
