The reaction πN → ωN in a dynamical coupled-channel approach
This talk is on a refined investigation on light flavor meson-baryon scatterings, using a dynamical coupled-channel approach, i.e. the Jülich-Bonn model. The previous channel space of πN, πΔ, σN, ρN, ηN, KΛ and Kσ is extended by adding the ωN final state. The spectra of N* and Δ resonances are extra...

| Summary: | This talk is on a refined investigation on light flavor meson-baryon scatterings, using a dynamical coupled-channel approach, i.e. the Jülich-Bonn model. The previous channel space of πN, πΔ, σN, ρN, ηN, KΛ and Kσ is extended by adding the ωN final state. The spectra of N* and Δ resonances are extracted, based on the result of a global fit to a worldwide collection of data, in the energy region from the πN threshold to center-of-mass energy z = 2.3 GeV (approximately 300 parameters against 9000 data points). A negative value of the ωN elastic spin-averaged scattering length has been extracted. |
