Summary

KN dispersion relations, evaluated with the correct Y o * effective-range formula, give g Λ 2 KN≈7.4 as against the value 4.8 of Lusignoliet al. SomeT=0,P-wave is also needed.

Riassunto

Le relazioni di disperisione KN, valutate con la corretta formula del range effecttivo dell' Y o * , dano g Λ 2 KN≈7.4 in contrasto col valore 4.8 di Lusignoliet al. È necessaria anche una certa quantità di ondaP, T=0.

Реаюме

Дисперсионные соотношения для KN, которые введены с помощью формулы с правильными эффективными размерами Y o * , дают значение величины\(g_{\Lambda \bar K\mathcal{N}}^2 \approx 7.4\), по сравнению с величиной 4,8, полученной лусиньоли и др. Необходима также некоторая примесьP волны приT=0.
