In this paper we present the results of an analysis of strange-particle production in π−p collisions leading to two charged final particles and at least one strange neutral decay. The sample consists

We present a study of A − 2 →K O S K − from the reaction π − p→K O S K − p at 4.5 GeV/ c in the 82-in. hydrogen bubble chamber. From a sample of 542 events from this final state, the mass (and its possible fine structure), width, production distribution and decay correlations of A − 2 are examined.
