Inclusive phi meson production, the parton fusion model and strange quark structure functions
Abstract
The parton fusion model is used to describe the longitudinal differential cross section of hadronic phi production. The cross section for phi production in pi (+or-) p, p (-) p, and K (+or-) p interactions is evaluated in the model by using structure functions for the constituents of the interacting particles. A comparison between the model and high statistics data in the Feynman x range 0 less than x sub F (phi) less than 0.4 allows the determination of the strange valence quark distribution in pi mesons, which appears to be harder than the light sea quark distribution. The comparison also shows that a significant part of inclusive phi production is due to the OZI allowed fusion of strange quarks, while the OZI inhibited fusion diagrams are strongly suppressed.
