Complex phase structure of the meson-baryon -matrix
Shahab Razavi, K. Nakayama
The full complex phase structure of the meson-baryon reaction amplitude in coupled channels approach is investigated, including also the photon-baryon channel. The result may be vi…
Eta photoproduction in a combined analysis of pion- and photon-induced reactions
D. Rönchen, M. Döring, H. Haberzettl +3
The final state is isospin-selective and thus provides access to the spectrum of excited nucleons without being affected by excited states. To this end, the world database…
reaction and hyperon resonances
Benjamin C. Jackson, Yongseok Oh, H. Haberzettl +1
The reaction is studied for center-of-momentum energies ranging from threshold to 3 GeV in an effective Lagrangian approach that includes the hyperon - a…
Hadronic description for Omega baryon photoproduction
Hui-Young Ryu, Atsushi Hosaka, H. Haberzettl +3
In the present work, we investigate subsequential production of three kaons and baryon based on an effective Lagrangian approach. We only consider the intermediate states wit…
Gauge-invariant theory of two-pion photo- and electro-production off the nucleon
Helmut Haberzettl, Kanzo Nakayama, Yongseok Oh
A field-theoretical description of the photoproduction of two pions off the nucleon is presented that applies to real as well as virtual photons in the one-photon approximation. Th…
Coupled-channel dynamics in the reactions piN --> piN, etaN, KLambda, KSigma
D. Rönchen, M. Döring, F. Huang +6
Elastic piN scattering and the world data of the family of reactions pi^- p --> eta n, K^0 Lambda$, K^0 Sigma^0, K^+ Sigma^-, and pi^+ p --> K^+ Sigma^+ are described simultaneousl…
