Abstract

Measurements of Ks0, Λ and {Mathematical expression} 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 Feynman x and transverse momentum squared as well as correlations between the V0 and the trigger particle are presented. The results are compared and found to be in agreement with Ks0, Λ and {Mathematical expression} 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-pt collisions. Our results can be well interpreted within the dual topological unitarization model.
