ON THE PROBLEM OF INVESTIGATING THE INTERACTION BETWEEN π MESONS AND HYPERONS

It is shown that use of the unitary property of the S matrix makes it possible to obtain some information about the scattering of π mesons by Λ and Σ hyperons from an analysis of the data on the interaction of K mesons with nucleons. The possibility of studying the π−Λ and π−Σ interactions by examining peripheral collisions of hyperons with nucleons is discussed.
