Abstract: (Elsevier)

We obtain information on the I = 0, J = 0 and I = 1, J = 1 ππ − K K partial waves via dispersion relations for πK backward scattering and for the ππ− K K partial waves. The ϱ coupling corresponds to G ϱ KK / G ϱππ = 1.3 ± 0.3 while the ϵ exchange amplitude is very small for t ≲ 15 μ 2 and is poorly determined for large t values. The invariant amplitudes below the s -, t - and u -channel thresholds are in good agreement with current algebra.
