Radiative hyperon decays as a test of nonleptonic weak-interaction models

Радиационные распады гиперонов, как проверка моделей нелептонных слабых вэаимодействий

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

Summary

We discuss decays of the type B → B′ + γ with |ΔS|=1 as a means of studying the weak-mass transition. Only transitions involving neutral hyperons are sensitive to this term. We also discuss the direct-emission amplitudes in relation to models of nonleptonic weak interactions.

Riassunto

Si discutono i decadimenti del tipo B → B′ + γ con |ΔS|=1 come mezzi per studiare le transizioni di massa debole. Solo le transizioni che coinvolgono iperoni neutri sono sensibili a questo termine. Si discutono anche le ampiezze di emissione diretta in relazione ai modelli delle interazioni deboli non leptoniche.

Реэюме

Мы обсуждаем распады типа B → B′ + γ c |ΔS|=1, как средство для иэучения скабого массового перехода. Только переходы, включаюшие нейтральные гипероны, являются сушественными к зтому члену. Мы также обсуждаем амплитуды прямой змиссии в свяэи с моделями нелептонных слабых вэаимодействий.
