Abstract: (Elsevier)

The equivalence of low-energy P-wave πN scattering in soliton models with the well-established Δ-isobar model is shown to hold even if all constraints on redundant collective variables are ignored. This provides strong support for the unusual (time- derivative) form of meson-baryon coupling in such models, and for the expectation that the soliton description of πN-scattering can be reliably extended down to pion threshold energies ina technically simple way.

pi nucleon: elastic scattering
elastic scattering: pi nucleon
scattering amplitude: partial wave
partial wave: scattering amplitude
Delta(1232): isobar model
model: soliton
Skyrme model
sigma model: nonlinear
Born approximation
coupling: (baryon meson)
