Joint production of ? mesons and? ,? 0,p, $\bar p$ ,K s 0 andK in hadronic interactions

The joint production of ϕ mesons andπ±,π0,p,\(\bar p\),K s 0 andK± is investigated using a sample of 600,000 inclusive ϕ meson events obtained in hadron Be interactions with incidentπ±,p,\(\bar p\) andK± beams. Evidence is presented for the joint production of ϕ mesons and strange particles produced with non-strange incident beams. With incidentK± beam the number of additional strange particles is suppressed. The results are found to be in agreement with the qualitative predictions of a parton fusion model. The comparison with the Lund model for lowpT processes is fair.
