“…This means that the magnitudes of the s-and p-wave amplitudes in this channel are given correctly but their interference term has the wrong sign. The same features apply to the channel π − p → K 0 Λ where the data stem from [25]. It may be that introduction of the S 11 (1650)-resonance coupling to KΛ (and possibly to KΣ) is necessary here.…”

Chiral SU(3) dynamics with coupled channels: inclusion of p-wave multipoles

We extend our recent non-perturbative chiral SU(3) coupled channel approach to pion-and photon-induced η-and K-meson production off protons by including all strong and electromagnetic p-wave multipoles. We identify the p-wave amplitudes of the next-to-leading order SU(3) chiral meson-baryon Lagrangian with a coupled channel potential which is iterated to infinite orders in a separable Lippmann-Schwinger equation. Our approach to η-and K-photoproduction introduces no additional free parameters. By adjusting a few finite range parameters and the unknown parameters in the Lagrangian, we are able to simultaneously describe a very large amount of lowenergy data. These include the total and differential cross sections of the π-inducedThe polarization observables measured in η-and K-photoproduction are particularly sensitive to interference terms between the s-and p-wave multipoles. The total cross section data are remarkably well reproduced in all channels. There remain, however, some open questions concerning details of angular distributions and polarization observables.

“…Fitted parameters are masses of resonances and coupling constants. The database contained the EPECUR data, total cross-sections for π -p→ηn [10] and data on differential cross sections for π -p→KΛ with πp→KΣ [11][12][13][14]. To be consistent with data on elastic πN scattering at energies below EPECUR data, we include in the database single energy solutions from WI08 partial wave analysis.…”

The new block of high precision data from EPECUR Collaboration is presented. The data has better than 1 MeV resolution in the invariant mass and show some interesting structure for negative pions. The multichannel K-matrix analysis allows explain this structure by two narrow (~20 MeV) resonances with masses 1686 and 1710 MeV. The influence of these resonances on the other channels is discussed also.
