Certain tests for possible angular momentum nonconservation in theweak interactions of strange particles are analysed for feasibility. Available evidence from:a) correlation between the Λ-Σ0 polarizations in the process Σ0 → Λ+γ, andb) \(\bar p\)p annihilation at rest into neutral kaons, does not indicate angular momentum nonconservation. Further evidence should be obtainable from:a) line shapes of X-rays from K-mesic atoms,b) regeneration ofKs from K L (or its absence) due to magnetic fields, andc) γ-rays from excited hypernuclei.

Проверка несохранения момента в слабых вэаимодействиях адронов


Аналиэируется проверка воэможного несохранения момента в слабых вэаимодействиях странных частиц. Имеюшиеся зкспериментальные данные иэa) корреляции между Λ-Σ0 поляриэациями в процессе Σ0 → Λ+γ,b) AAAp аннигиляции в нокое в нейтральные каоны не укаэывают на несохранение момента. Дальнейщие подтверждения должны быть получены иэa) форм линий рентгеновских лучей иэ К-меэонных атомов;b) регенерации K S иэ K L (или иэ ее отсутствия), обусловленной магнитными полями, иc) γ-лучей иэ воэбужденных гиперядер.


Si esamina se è possibile eseguire alcune verifiche della possibile non conservazione del momento angolare nelle interazionideboli delle particelle strane. Le testimonianze datecia) dalla correlazione fra le polarizzazioni Λ-Σ0 nel processo Σ0 → Λ+γ,b) dall’annichilazione AAAp in quiete in kaoni neutri, non danno indizi della non conservazione del momento angolare. Si potrebbero ottenere ulteriori testimonianzea) della forma delle linee dei raggi X emessi dagli atomi K-mesici,b) dalla rigenerazione delKS dal K L (o la sua assenza) dovuta a campi magnetici ec) dai raggi γ emessi dagli ipernuclei eccitati.
