Hyperfragment production in K-meson absorptions at rest in nuclear emulsions. Mesic decays

  • J. Sacton
Article

Summary

The results of the analysis of 26 mesic hyperfragment decays found in a sample of 2 236 K-meson stars (excluding K ρ - ) are given. 9 hyperfragment decays have been uniquely identified. Among these, a new decay mode of the8LiΛ hyperfragment has been observed. We also mention the possible existence of a6HeΛ hyperfragment.

Riassunto

Si espongono i risultati dell’analisi del decadimento di 26 iperframmenti mesici trovati in un gruppo di 2 236 stelle da mesoni K (esclusi i K ρ - ). Si sono identificati soltanto 9 decadimenti di iperframmenti. Fra di essi si è osservato un nuovo modo di decadimento dell’iperframmento8LiΛ. Menzioniamo anche la possibilità dell’esistenza dell’iperframmento6HeΛ.
