Seeing gluons in decay ofP-wave quarkonium

Глюоны в распадаP-волнового кваркониума

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

Summary

In view of the exceptionally favourable kinematics, we present a complete study of the hadron distribution from the decay ofP-wave\(Q\bar Q\) bound states, originating from radiative decays of higherlyingS-wave states (23 S 1 → γ+3 P,3 P → hadrons).

Riassunto

In relazione alla cinematica eccezionalmente semplice, si presenta uno studio completo della distribuzione di adroni nel decadimento di stati legati d’ondaP di quark e antiquark pesanti, quali prodotti di decadimenti radiativi di statiS superiori (23 S 1 → γ+3 P,3 P → adroni).

Реэюме

В виду исключительно благоприятной кинематики, мы проводим полное исследование распределения адронов, обраэованных при распаде Р-вол-новых свяэанных состояний\(Q\bar Q\) которые воэникли иэ радиационных распадов высоколежашихS-волновых состояний (23 S 1→γ+3 P,3 P→ адроны).
