A review of the η-η′ mixing problem

Обэор проблемы η-η′ смещивания

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

Summary

We probe the consequences of η-η′ mixing in all two-body and three-body meson decays and in high-energy charge and hyper-charge exchange reactions.

Riassunto

Si indagano le conseguenze della miscela ηη′ su tutti i decadimenti dei mesoni a due e tre corpi e sulle reazioni di scambio della carica e dell’ipercarica ad alta energia.

Реэюме

Мы исследуем следствия η-η′ смещивания во всех двухчастичных и трехчастичных распадах меэонов и в реакциях переэарядки и обмена гиперэарядом при высоких знергиях.

  27. Ref. (8) gives 0.13 for (21), but a complete set of measured branching ratios corresponds to omitting the high-statistics spark chamber measurement of η→π+π−γ/η→π+π−π0 because of possible systematic errors. This leads to 0.16 ± 0.02 (21)—see ref. (23) for details.
