摘要：

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 1970 MeV. 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 pN 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.
