Abstract
Elastic {pi}N scattering and the world data of the family of reactions {pi} {sup -} p {yields} {eta}n, K {sup 0} {Lambda}, K {sup 0} {Sigma} {sup 0}, K {sup +} {Sigma} {sup -}, and {pi} {sup +} p {yields} K {sup +} {Sigma} {sup +} are described simultaneously in an analytic, unitary, coupled-channel approach. SU(3) flavor symmetry is used to relate both the t - and the u - channel exchanges that drive the meson-baryon interaction in the different channels. Angular distributions, polarizations, and spin-rotation parameters are compared with available experimental data. Partial-wave amplitudes are determined and the resonance content is extracted from the analytic continuation, including resonance positions and branching ratios, and possible sources of uncertainties are discussed. The results provide the final-state interactions for the ongoing analysis of photo- and electroproduction data. (orig.)
