On the interpretation of the K−-meson interaction in nuclear emulsion

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Observed frequencies of pions emitted by K− captures at rest in nuclear emulsion are used for an estimation of the percentage of 1 interactions. It is shown that a value of 20% is an upper limit for the percentage of 2 interactions. Simultaneously it turns out that the capture must occur preferentially at the nuclear surface. We determine a branching ratio for the production of different kinds of hyperons in the 1 interactions.

Riassunto

Le frequenze osservate dei pioni emessi da catture K− in riposo in emulsioni nucleari vengono usate per stimare la percentuale di interazioni I. Si dimostra che un valore di 20% è il limite superiore per la percentuale di interazioni 2. Nello stesso tempo risulta che la cattura deve accadere a preferenza sulla superficie nucleare. Si determina anche il rapporto dibranching per la produzione di diverse specie di iperoni nella interazione I.
