Analysis of the reaction π+-nucleon→π+π+π-π0π0-nucleon at 3.5GeV/c

Creators

Description

Complete π0's reconstruction in heavy liquid bubble chamber has allowed to study the π+π+π-π0π0-nucleon channel produced by π+ of 3.5GeV/c. Individual particle properties as well as various angular and mass correlations have been studied. The main results are: importante ω0 production, π0π0 strong correlation, fit of CLA-type phenomenological model (Chang Hong Mo-Loskiewicz-Allison model) which accounts well for the experimental data. The two (correlated) neutral pions are preferentially produced at the lower vertices

Abstract (French)

La reconstruction complete des π0 en chambre a bulles a liquide lourd a permis d'etudier la reaction π+nucleon→nucleon π+π+π-π0π0 a 3,5 GeV/c. On etudie les caracteristiques des particules individuelles ainsi que les correlations d'angle et de masse entre ces particules. Les principaux resultats sont: l'importante production de ω0, la forte correlation entre les deux π0, l'ajustement des donnees par le modele phenomenologique (Chang Hong Mo-Loskiewicz-Allison). Les deux π0 sont emis preferentiellement pres du vertex du nucleon
