Summary
In the present paper we report some results on the interactions of high energy K−-mesons in emulsion. The results concern the energy spectrum and angular distribution of the re-emitted K−, the π-meson production, the mean life time of Σ±, Σ+ and σ− hyperons, the nuclear scatterings of Σ± and the up-down asymmetry in the decay of the Σ+ hyperon.
Riassunto
In questo lavoro sono dati alcuni risultati sulle interazioni di K− di alta energia con i nuclei dell’emulsione. In particolare vengono dati lo spettro angolare e di energia dei K− riemessi; alcuni dati sulla produzione di pioni da parte dei K−; la vita media degli iperoni Σ±, Σ+ e Σ−; la sezione d’urto per lo scattering nucleare degli iperoni Σ± e l’asimmetria, rispetto al piano di produzione del Σ+, dei protoni derivanti dal decadimento: Σ+→p+π0.

No sure example of Ξ−hyperon was found but in 8 cases out of 2945 stars it was not possible to distinguish between Σ− and Ξ−-decays. The value of the cross section for Ξ− production by K− given byAlvarez (2) is 0.02 mb per nucleon: according to this figure the number of Ξ−-hyperons produced in the 2945 interactions studied by us in the emulsion would be of the order of one or two, so that our result is not inconsistent with the very low value of the cross-section for Ξ− production.
