Associated production of heavy flavours

Ассоциированное рождение тяжелых флаворов

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

Summary

We present some detailed estimates of associated heavy-flavour bound states produced in e+e− annihilations. The calculation is done to lowest order in QCD and we attempt to clarify some ambiguities concerning its range of applicability. The QCD estimates are compared with competing QED (two-photon exchanges) and weak (t decay) channels.

Riassunto

Si presentano alcune stime dettagliate degli stati legati associati con sapori pesanti prodotti in annichilazioni e+e−. Il calcolo è eseguito fino agli ordini inferiori nella QCD e si cerca di chiarire alcune ambiguità riguardanti il suo intervallo di applicabilità. Le stime della QCD sono confrontate con i canali concorrenti della QED (sambi di due fotoni) e deboli (decadimento del t).

Резюме

Мы предлагаем некоторые подробные оценки для ассоцированных связанных состояний тяжелых флаворов, образованных в процессе e+e− аннигиляции. Вычисление троводится в низшем порядке квантовой хромодинамики. Мы пытаемся выяснить неоднозначности, касающиеся области применимости. Оценки в рамках квантовой хромодинамики сравниваются с конкурирующими каналами квантовой электродинамики (обмен двумя фотонами) и слабыми каналами (t распад).
