Parity non-conservation in pion production

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

In this note we calculate using the method of Weizsäcker-Williams the pion production asymmetry in the scattering of pions on oriented nucleons due to a possible parity violation in the pion-nucleon interaction. One gets an upper bound for the asymmetry using the upper bounds for the parity violation in pion-nucleon scattering calculated byFubini andWalecka in the assumption of the maximum parity violation in K-production. The result obtained is not inconsistent with the result of a recent pion production experimental results.

Riassunto

Si calcola col metodo di Weizsäcker-Williams l’asimmetria di produzione di pioni nell’urto di nucleoni orientati dovuta a una eventuale violazione di parità nell’interazione pione nucleone. Si ottiene un limite superior nell’asimmetria usando i limiti superiori sulla violazione di parità in scattering pione nucleone calcolati da Fubini e Walecka nell’ipotesi di massima violazione di parità nella produzione di K. Il risultato ottenuto non è inconsistente con quello di un recente esperimento per rivelare un tale effetto.
