CouldSU 3 be an exact reduced-vertex symmetry?

Может ли SU3 являться точной симметрией приведенной верщины?

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

Summary

We reinvestigateSU 3 predictions for the most reliable data on resonance decays for both linear and quadratic meson mixing. Contrary to prevalent opinion, we find no convincing evidence ofSU 3 violation although an essential redefinition of the reduced matrix element for decuplet decays is required.

Riassunto

Si riesaminano le predizioni diSU 3 per i dati più attendibili sui decadimenti delle risonanze sia per la miscela mesonica lineare che per quella quadratica. In contrasto con le opinioni prevalenti, non si trova alcuna convincente prova della violazione diSU 3 sebbene sia necessaria una ridefinizione dell’elemento di matrice ridotto per i decadimenti di decupletto.

Реэюме

Мы эаново исследуем SU3 предскаэания для больщинства надежных данных по реэонансным распадам для линейного и квадратичного меэонного смещивания. В противоположность обшепринятому мнению, мы не получили убедительных подтверждений нарущения Su3, хотя требуется сушественно новое определение приведенного матричного злемента для распадов декуплета.
