Meson decays in a Bethe-Salpeter model

Распады мезонов в модели Бете-Салпитера

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

Summary

We show that the Bethe-Salpeter amplitudes derived from a kernel with the spinor structure γ5×γ5 in the harmonic-oscillator approximation give good results for the meson decays. If one includes the weight factors from the quark colours, strong, electromagnetic and weak meson decays are well described by an effective quark massm q=1 GeV.

Riassunto

Si mostra che le ampiezze di Bethe-Salpeter derivate da un nocciolo con la struttura spinoriale γ5×γ5 nell’approssimazione dell’oscillatore armonico danno buoni risultati per i decadimenti mesonici. Se si includono i fattori di peso derivati dai colori dei quark, i decadimenti mesonici forti, elettromagnetici e deboli sono ben descritti da una massa effettiva del quarkm q=1 GeV.

Резюме

Мы показываем, что амплитуды Бете-Салпитера, выведенные из ядра со спинорной структурой γ5×γ5, в приближении гармонического осциллятора дают хороцие результаты для распадов мезонов. Используя весовые факторы из цветов кварков, силяные, єлектроматнитные и слабые распады мезонов хорошо описываются с помощью эффективной массы кваркаm q=1ГєВ
