Summary

The reactions pp→pN*(1518)→ppπ+π and pp→ →pN*(1688)→pπ+π at 5.5 GeV/c were studied. Total and differential cross-sections were calculated with the unmodified and modified (absorptive0 one-pion exchange (OPE) models using explicit wave functions for the spin-3/2 and spin-5/2 particles. The agreement between the experimental and calculated angular distributions is imposed with the absorption modification to the OPE model.

Riassunto

Si sono studiate le reazioni pp→pN*(1518)→ppπ+π e pp→ →pN*(1688)→pπ+π a 5.5 GeV/c. Si sono calcolate le sezioni d'urto totale e differenziale con i modelli di scambio di un pione (OPE) non modificato e modificato (con assorbimento) usando la funzione d'onda esplicita per le particelle di spin 3/2 e 5/2. Si ottiene l'accordo fra le distribuzioni angolari sperimentale e calcolata imponendo al modello OPE la modificazione assorbitiva.
