Weak form factors from pion electroproduction at threshold: A phenomenological approach

Слабые форм-факторы из электророждения пионов на пороге: Феноменологический подход

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

Summary

We re-analyse data of threshold electroproduction assuming the transverse cross-section to be described exactly by a semi-phenomenological model previously adopted. The resulting «experimental» curve of the longitudinal cross-section is analysed to obtain information on the induced pseudoscalar form factorG P.

Riassunto

Dati di elettroproduzione a soglia sono rianalizzati supponendo che la parte trasversale sia data esattamente da un modello semifenomenologico precedentemente adottato. La curva «sperimentale» risultante per la parte longitudinale è analizzata per ottenere informazioni sul fattore di forma pseudoscalareG P.

Резюме

Заново анализируются данные злектророждения на пороге, предполагая, что поперечное сечение описываетсяточно полуфеноменологической моделью, предложенной ранее. Анализируется результируюшая «экспериментальная» кривая для продольного сечения, чтобы получить иноормацию об индуцированном псевдоскалярном форм-фактореG P.
