“…The inelastic π − p scattering process leading to the nη final state was reported from several experiments [25][26][27][28] and [29,30]. Above 1.8 GeV, large discrepancies between the data [27,30] show up. The data from [29] cover extreme backward angles and are partly incompatible with all other results.…”

Abstract. Masses, widths and photocouplings of baryon resonances are determined in a coupled-channel partial wave analysis of a large variety of data. The Bonn-Gatchina partial wave formalism is extended to include a decomposition of t-and u-exchange amplitudes into individual partial waves. The multipole transition amplitudes for γp → pπ 0 and γp → nπ + are given and compared to results from other analyses.

“…The data are taken from Refs. [39,41,42,49,50,51,52]. meson-exchange model [25] includes only a few low-mass resonances and, consequently, does not agree with the total charge exchange cross sections above 1.5 GeV, cf.…”

The amplitudes for the pion-nucleon charge exchange reaction of the Karlsruhe-Helsinki and the George-Washington-University partial wave analyses are compared with those of a Regge-cut model with the aim to explore the possibility to provide high energy constraints for theoretical baryon resonance analyses in the energy region above 2 GeV.

P -wave excited baryons from pion- and photo-induced hyperon production

Abstract. We report evidence for N (1710)P11, N (1875)P11, N (1900)P13, ∆(1600)P33, ∆(1910)P31, and ∆(1920)P33, and find indications that N (1900)P13 might have a companion state at 1970 MeV. The controversial ∆(1750)P31 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) [1] and the Carnegie-Mellon (CM) [2] analyses but were challenged recently by the Data Analysis Center at GWU [3]. Our analysis is constrained by the energy independent πN scattering amplitudes from either KH84 or GWU. The two πN amplitudes from KH84 or GWU, respectively, lead to slightly different πN branching ratios of contributing resonances but the debated resonances are required in both series of fits.
