Photoproduction of mesons is an excellent tool for the study of nucleon resonances.
Complementary to pion induced reactions, photoproduction on the free proton contributes to …

The production of η and η′ mesons in photon-and hadron-induced reactions on free and
quasi-free nucleons and on nuclei is reviewed. The extensive database on γ N→ η N, for …

We identify the leading s-wave amplitudes of the SU (3) chiral meson-baryon Lagrangian
with an effective coupled-channel potential which is iterated in a Lippmann-Schwinger …

Starting from a unitary effective Lagrangian model for the meson-nucleon scattering
developed in T. Feuster and U. Mosel, Phys. Rev. 58, 457 (1998), we come to a unified …

Searches for a nucleon decay into a charged antilepton (e+ or μ+) plus a light meson (π 0, π-
, η, ρ 0, ρ-, ω) were performed using the Super-Kamiokande I and II data. Twelve nucleon …

We extract nucleon resonance parameters from an effective Lagrangian model employing
the K-matrix approximation. To this end we analyze simultaneously all available data for …

The photoproduction of η-mesic He 3 has been investigated using the TAPS calorimeter at
the Mainz Microtron accelerator facility MAMI. The total inclusive cross section for the …

We present new Σ beam asymmetry data for η meson photoproduction on the proton, using
a novel tagged, laser backscattered, linearly polarized photon beam up to 1.1 GeV. The data …

New results on quasi-free η photoproduction on the neutron and proton bound in a deuteron
target are presented. The γn→ ηn quasi-free cross section reveals a bump-like structure …

Quasifree photoproduction of η mesons off nucleons bound in the deuteron has been
measured with the CBELSA/TAPS detector for incident photon energies up to 2.5 GeV at the …
