Pion multiplicity in antinucleon annihilation

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Pion multiplicity in antinucleon annihilation has been calculated using Dyson’s hypothesis of pion-pion resonance interaction. The percentage of K-mesons was also evaluated supposing that their volume of interaction has a radius given by the Compton wavelength of K-mesons. Results are in reasonable agreement with experimental data.

Riassunto

Si è calcolata la molteplicità pionioa nell’annichilazione di un antinuoleone ed tm nucleone introducendo un’ipotesi proposta da Dyson riguardante una interazione di risonanza pione-pione. Si è calcolata inoltre la percentuale di mesoni K prodotti supponendo ce il raggio del loro volume d’interazione sia dato dalla lunghezza. d’onda Compton del mesone K stesso. I risultati oosi ottenuti sono in buon acoordo con quelli sperimentali.
