Anisovich, E. Klempt, V. Nikonov, A. Sarantsev, U. Thoma] Abstract.: We report evidence for N(1710)P 11 , N(1875)P 11 , N(1900)P 13 , $ \Delta$(1600)P 33 , $ \Delta$(1910)P 31 , and $ \Delta$(1920)P 33 , and find indications that N(1900)P 13 might have a companion state at 1970MeV. The controversial $ \Delta$(1750)P 31 is not seen. The evidence is derived from a study of data on pion- and photo-induced hyperon production, but other data are included as well. Most of the resonances reported here were found in the Karlsruhe-Helsinki (KH84) and the Carnegie-Mellon (CM) analyses but were challenged recently by the Data Analysis Center at GWU. Our analysis is constrained by the energy-independent $ \pi$ N scattering amplitudes from either KH84 or GWU. The two $ \pi$ N amplitudes from KH84 or GWU, respectively, lead to slightly different $ \pi$ N branching ratios of contributing resonances but the debated resonances are required in both series of fits.
