Combined Analysis of Near-Threshold Production of omega and phi Mesons in Nucleon-Nucleon Collisions within an Effective Meson-Nucleon Model

Abstract

Vector meson ($V=\omega ,\varphi$) production in near-threshold elementary nucleon-nucleon collisions $pp\to ppV$, $pn\to pnV$ and $pn\to dV$ is studied within an effective meson-nucleon theory. It is shown that a set of effective parameters can be established to describe fairly well the available experimental data of angular distributions and the energy dependence of the total cross sections without explicit implementation of the Okubo-Zweig-Iisuka rule violation. Isospin effects are considered in detail and compared with experimental data whenever available.
