PCAVC hypothesis and the pion-lambda interaction

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The partially-conserved axial-vector current hypothesis (PCAVC) is used to derive a consistency condition on π-Λ scattering, which is then examined quantitatively, using the results of a recent analysis of the low-energy π-Λ interaction. The consistency condition isA π-Λ(ν=0,ν B =0,k 2=0)=0 and we findA π-Λ=2±3. The result is comparable with that obtained by Adler for π-\(\mathcal{N}\) scattering.

Riassunto

Si usa l’ipotesi della corrente vettoriale assiale parzialmente conservata per dedurre una condizione di consistenza allo scattering π-Λ, che si esamina poi quantitativamente, facendo uso dei risultati di una recente analisi dell’interazione π-Λ di bassa energia. La condizione di consistenza èA π-Λ(ν=0,ν B =0,k 2=0)=0 e si trovaA π-Λ=2±2, Il risultato è paragonabile con quello ottenuto da Adler per lo scattering π-\(\mathcal{N}\).
