Abstract

The method, based on the techniques of current algebra and dispersion relations, is used for calculating the ratio of thed ands wave coupling of the vertex <K A |J π|K *>. We obtain a limitation for the pole approximation and applying the general results ofLai [1] the Γ(K *Kπ) and Γ(K A K *π) decay widths are calculated in good agreement with recent experimental data. In our calculation we apply the Weinberg broken sum rules.

Резюме

Для вычисления соотншения д и с волновой связи вершинх <K A |J π|K *> применяются техника алгебры токов и дисперсионные соотношения. Получено ограничение для полюсного приближения. Применяя общие результаты Лаи [1], вычислялись ширины распадов Г (K *Kπ) и Г (K A K *π), находящиеся в хорошем согласии с опытными данными. В вычислениях использовано нарушенные правила сумм Вейнберга.
