Résumé : We present a study of six- and seven-body final states among the K+p interactions at 5 GeV/c incident K+ momentum. Results on cross sections, resonance and single-particle productions are given. Charge dependent angular correlations for pairs of pions occur as in pp and π+p interactions (the so called GGLP effect). In contrast, no dependence on the charge is observed in the angular correlations between kaons and pions. The influence of the production of K* and N* resonances on these angular correlations is investigated. The predictions of a multi-Regge Model (CŁA) are compared to the experimental results. © 1969.
