A vector contribution to the decay Σ− → Λ+e−+\(\bar \nu \) e e

Векторный вклад в распад Σ− → Λ+e−+\(\bar \nu \) e e

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

Summary

Recent experimental data indicate that the vector contribution to the decay Σ− → Λ+e−+\(\bar \nu \) e is not zero. This can be readily explained within the framework of the conserved vector-current hypothesis if isospin mixing between the Σ0 and Λ occurs in an amount corresponding to a mixing angleϑ=(0.14±0.07) radians.

Riassunto

Recenti dati sperimentali indicano che il contributo vettoriale al decadimento Σ− → Λ+e−+\(\bar \nu \) e non è nullo. Ciò può essere facilmente spiegato nel contesto dell’ipotesi della conservazione della corrente vettoriale se la miscela di isospin fra Σ0 e Λ avviene per un ammontare corrispondente all’angolo di miscela ϑ=(0.14±0.07) radianti.

Реэюме

Недавние зкспериментальные данные укаэывают, что векторный вклад в распад Σ− → e−+\(\bar \nu \) e не есть нуль. Это может быть легко общяснено в рамках гипотеэы сохраняюшегося векторного тока, если иэоспиновое смещивание между Σ0 и Л присутствует в количестве, соответствуюшем углу смещиванияϑ=(0.14±0.07) радиан.
