Summary

We study a unitarization method in connection with the recently proposed Veneziano-like models for the pion electromagnetic form factor. Using as input the model proposed by Suura, good agreement is obtained with the experimental data in the timelike region.

Унитарность и пионный форм-фактор в моделях, подобных модели Венециано

Резюме

Мы исследуем метод унитаризации в связи с недавно предложенными моделями, подобными модели Венециано, для электромагнитного формфактора. Используя, как исходное, модель, предложенную Суура, получается хорошее согласие с экспериментальными данными во времени-подобной области.

Riassunto

Si studia un metodo di unitarizzazione in connessione coi modelli alla Veneziano recentemente proposti per il fattore di forma elettromagnetico del pione. Usando come punto di partenza il modello proposto da Suura si trova un buon accordo con i dati sperimentali nella regione temporale.
