| Abstract: | The production of η(550) and ω(780) mesons is studied in π±p interactions at 16 GeV/c and K?p interactions at 10 and 16 GeV/c. Cross sections for exclusive channels are presented, and for the π+p data differential cross sections are given for quasi-inclusive production where the η or ω is required to be accompanied by charged particles only. Close similarities are observed between η, ω and also ?0(770) production in terms of longitudinal and transverse variables. By a rough estimate, the η, ω and ?0 inclusive yields are found to be in the ratio 0.32 : 0.85 : 1, respectively, for 16 GeV/cπ+p collisions. For non-peripheral production we estimate this same ratio to be 0.34 : 0.9 : 1. |
