Effect of a phenomenologicalS-wave pion-pion interaction on the photoproduction of a pion pair in a coulomb field

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The photoproduction of a pair of pions in the Coulomb field of a nucleus is studied. It is shown to be very sensitive to the effect of a final-stateS-wave pion-pion interaction. Using various models for such an interaction, the double differential cross-section for producing a pion pair in a Coulomb field is calculated and shown to be comparable to the nuclear field production for small momentum transfers.

Riassunto

Si studia la fotoproduzione di una coppia di pioni nel campo coulombiano di un nucleo. Si dimostra che è molto sensibile agli effetti di un’interazione pione-pione di ondaS nello stato finale. Servendosi di vari modelli di questa interazione, si calcola la sezione d’urto differenziale doppia per la produzione di una coppia di pioni in un campo coulombiano e si dimostra che essa è paragonabile alla produzione del campo nucleare per piccoli momenti trasferiti.
