Threshold enhancements and resonant effects in exclusive γγ reactions

Пороговые увеличения и резонансные эффекты в эксклюзивных γγ реакциях

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

Summary

In connection with the σσ enhancement recently observed at 1.6 GeV we estimate and discuss contributions of threshold effects and resonances to the cross-sections of several exclusive channels like γγ→VV′, Vγ, νππ, KK* and πA1.

Riassunto

In connessione con l'incremento σσ osservato recentemente a 1.6 GeV si stimano e si discutono i contributi degli effetti soglia e delle risonanze alle sezioni d'urto di parecchi canali esclusivi come γγ→VV′, Vγ, νππ, KK* e πA1.

Резюме

В связи с σσ увеличением, недавно обнаруженным при 1.6 ГэВ, мы оцениваем и обсуждаем вклады пороговых эффектов и резонансов в поперечные сечения для некоторых эксклюзивных каналов, таких как γγ→VV′, Vγ, νππ, KK* и πA1.
