Regge-pole theory of the photoproduction of pions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

In an attempt to apply a Regge-pole treatment to photoproduction it was found that in order to obtain the desired results massive photons have to be introduced into the theory thus allowing effects arising from longitudinal polarization of the photon. A new set of invariant amplitudes for the electroproduction of pions naturally suggest themselves from these considerations.

Riassunto

Nel tentativo di applicare il trattamento dei poli di Regge alla fotoproduzione, si è trovato che, per ottenere i risultati desiderati, si devono introdurre nella teoria fotoni dotati di massa, in modo da consentire gli effetti che derivano dalla polarizzazione longitudinale del fotone. Da queste considerazioni nasce naturalmente un nuovo gruppo di ampiezze invarianti per l’elettroproduzione dei pioni.
