Abstract The inclusive production ofK *±(890), ρρ(770), ω0(780) andf 0(1,270) mesons is studied in $$\bar pp$$ experiment at 32GeV/c in the MIRABELLE bubble chamber by the analysis of (K 0π±) and (π+π−) invariant mass distributions. The inclusive cross sections are σ(K *±)=2.45±0.30 mb, σ(ρ0)=8.8 ±0.9 mb, σ(ω+)≃6.2 mb, and σ(f 0)=2.2±0.7 mb. The C.M. longitudinal distribution of theK *±(890) is slightly shifted to the primary particles fragmentation regions; the ρ0 is produced more centrally. The studied mesons alone are responsible for 40% of final state poins. The production features of various resonances are compared with quark models predictions.
