Summary

An analysis is given of strange-particle production in collisions of 24.5 GeV/c protons with protons (c.m.s. total energy =6.72 GeV). It is based on 50 000 pictures taken with the CERN 30 cm hydrogen bubble chamber. Comparison is made with an experiment on π-p interactions at 16 GeV/c in the same chamber. The low transverse momenta previously found are confirmed-only positive hyperons have high transverse momenta. Partial cross-section are given.

Riassunto

Si espone un’analisi della produzione di particelle strane in collisioni di protoni di 24.5 GeV/c con protoni (energia totale nel s.c.m. = 6.72 GeV). Essa si basa su 50 000 fotografie eseguite con la camera a bolle a idrogeno di 30 cm del CERN. Si fa un confronto con un esperimento sulle interazioni π-p di 16 GeV/c eseguito colla stessa camera. Si confermano i deboli impulsi trasversali trovati in precedenza; solo gli iperoni positivi hanno impulsi trasversali elevati. Si dànno le sezioni d’urto parziali.
