The recent results from the Bonn-Gatchina group are presented and discussed. The analysis of the new data on the η and η′ photoproduction off proton firmly confirms the existence of three nucleon resonances with masses around 1900 MeV. The combined analysis of the data on the kaon proton collision reactions indicates the presence of new states which were missed in the analysis of the separate data sets.

Coupled Channel

Properties of the nucleon resonances are investigated within a coupled channel model of πN, γN → πN, ηN, KΛ, KΣ and ππN reactions. The pole positions and the residues of the nucleon resonances are extracted by using the analytic continuation of the scattering amplitudes.

Abstract A coherent study of e+e− annihilation into two (π+π−, K+K−) and three (π+π−π0, π+π−η) pseudoscalar meson production is carried out within the framework of resonance chiral theory in energy region E ≲ 2 GeV. The work of [L.Y. Dai, J. Portolés, and O. Shekhovtsova, Phys. Rev. D88 (2013) 056001] is revisited with the latest experimental data and a joint analysis of two pseudoscalar meson production. Hence, we evaluate the lowest order hadronic vacuum polarization contributions of those two and three pseudoscalar processes to the anomalous magnetic moment of the muon. We also estimate some higher-order additions led by the same hadronic vacuum polarization. Combined with the other contributions from the standard model, the theoretical prediction differs still by (21.6 ± 7.4) × 10−10 (2.9σ) from the experimental value.
