Generating functionals, Ward identities and scalar mesons

Образование функционалов, тождества Уорда и скалярные мезоны

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

Summary

We shall present a general and concise treatment of Ward identities in current algebra with broken symmetry. An application is also presented to the mass spectrum and leptonic decay constants of the scalar and pseudoscalar mesons.

Riassunto

Si presenta un trattamento generale e conciso delle identità di Ward dell'algebra delle correnti con rottura di simmetria. Si dà un'applicazione allo spettro di massa e alle costanti di decadimento leptonico dei mesoni scalari e pseudoscalari.

Резюме

Мы предлагаем обшее и сжатое рассмотрение тождеств Уорда в алгебре токов с нарушенной симметрией. Также приводится применение к массовому спектру и постоянным лептонного распада скалярных и псевдоскалярных мезонов.
