Abstract Measurements ofK s 0 , Λ and $$\bar \Lambda $$ production in π− nucleus (C, Cu, Pb) interactions are presented. The experiment was carried out with the streamer chamber spectrometer RISK using a π− beam of ∼40 GeV/c and a trigger requiring a secondary charged particle with transverse momentum above 1.1 GeV/c. Production cross sections, relative production rates and distributions of Feynmanx and transverse momentum squared as well as correlations between theV 0 and the trigger particle are presented. The results are compared and found to be in agreement withK s 0 , Λ and $$\bar \Lambda $$ data from untriggered π− p and π− C interactions, except for the relative production rate of antilambdas which is about to times larger in high-p t collisions. Our results can be well interpreted within the dual topological unitarization model.
