Eta decay

Распад эта-мезона

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

Summary

A method used previously to separate the Coulomb and tadpole contributions to the electromagnetic-mass differences is applied to the η decay problem. We find Γ(η→π+ππ0)=160 eV.

Riassunto

Si applica al problema del decadimento di eta un metodo usato precedentemente per separare i contributi di Coulomb e del grafico a girino alle differenzes di massa elettromagnetica. Si trova Γ(η→π+ππ0)=160 eV.

Резюме

Мртод, ранее использованный для разделения кулоновского и «головастикового» вкладов в электромагнитных разностях масс, применяется к проблеме распада эта-мезона. Мы получаем, что Γ(η→π+ππ0)=160 эВ.
