Separable potential model for nonK?N interactions at low energies
Result description
The effective separable meson-baryon potentials are constructed to match the equivalent chiral amplitudes up to the second order in external meson momenta. We fit the model parameters (low-energy constants) to the threshold and low-energy nonK p data. Inthe process, the nonK-?proton bound-state problem is solved exactly in the momentum space and the 1s level characteristics of the kaonic hydrogen are computed simultaneously with the available low-energy nonK p cross-sections. The model is also used todescribe the ??? mass spectrum and the energy dependence of the nonK n amplitude.
