Summary
We report a systematic study of π+p interactions at 1.59 GeV/c in the Saclay HBC 1801 at Saturne. The two-prong reactions enabled us to study ρ+ and\(\mathcal{N}_{33}^{* + + } \) production. These productions are compared with the predictions of the OPE model for the ρ+, and the Stodolsky-Sakurai model for\(\mathcal{N}_{33}^{* + + } \). In four-prong reactions,\(\mathcal{N}_{33}^{* + + } \) production is important, and we observed the associated production π+p→\(\mathcal{N}_{33}^{* + + } \eta \). Finally we give the cross-section values in all different channels.
Riassunto
Vengono esposti i tisultati di uno studio sistematico delle interazioni su protoni ottenute nella camera a bolle di 1801 a idrogeno di Saclay, esposta ad un fascio di π+ di 1.59 GeV/c al Saturno. Le reazioni a due rami hanno permesso di studiare le produzioni della ρ+ e dell’isobaro\(\mathcal{N}_{33}^{* + + } \) e di confrontarle con le predizioni del modello OPE per la ρ+ e del modello di Stodolski e Sakurai per l’isobaro\(\mathcal{N}_{33}^{* + + } \). Nelle reazioni a quattro rami è importate la produzione di\(\mathcal{N}_{33}^{* + + } \) ed è stata osservata la produzione associate π+p→\(\mathcal{N}_{33}^{* + + } \eta \). Infine vengono dati i valori delle sezioni d’urto per tutti i diversi processi.
