We present results of a new multichannel partial-wave analysis for pi N scattering in the c. m. energy range 1080 to 2100 MeV. This work explicitly includes eta N and K Lambda channels and the single pion photoproduction channel. Resonance parameters were extracted by fitting partial-wave amplitudes from all considered channels using a multichannel parametrization that is consistent with S-matrix unitarity. The resonance parameters so obtained are compared to predictions of quark models.
