Study of ambiguities in ${\pi }^{-}p\to \Lambda K^0$ scattering amplitudes

A. V. Anisovich, R. Beck, E. Klempt +4

Amplitudes for the reaction ${\pi }^{-}p\to \Lambda K^0$ are reconstructed from data on the differential cross section $d\sigma /d\Omega$, the recoil polarization $P$, and on the spin rotation parameter $β…
