The inclusive and semi-inclusive cross sections for K*±(890) and Σ±(1385) resonances are determined in p¯p interactions at 14.75 GeV/c. They account for a large fraction of the KS0 and Λ0 produced. The K*-resonance production also affects the low-pT2 distribution of inclusive KS0. The x distributions of the resonance production are studied in terms of a simple quark-recombination model.

We present a study of the inclusive production ofK*(892) and ∑t+-(1385)+cc at 3.6 GeV/c from$\bar p$p interactions. The sensitivity of the exposure is 35.4 events/μb. Longitudinal and transverse momentum distributions are presented. The indirect production ofKs0 from parentK* and that of Λ's from parent Σ(1385) are studied. The shape of thex distribution of Λ's for$p\xrightarrow{{\bar p}}\Lambda $ are calculated from$p\xrightarrow{p}\Lambda $ and$p\xrightarrow{{\pi ^ -}}\Lambda $ and compared with the experimental distributions. The difference of antiparticle production cross-section ofKs0 in the central region is compared with the expectation from Mueller-Regge formalism.

INCLUSIVE RESONANCE PRODUCTION IN 7.3-GEV/C ANTI-P P INTERACTIONS

We present results on inclusive baryon and meson resonance production in$\bar pp$ interactions at 7.3 GeV/c. Total inclusive and semi-inclusive cross sections are given for Δ(1232),∑*(1385), ϱ0,f andK*±(892) production. For the meson resonances separation into annihilation and non-annihilation components has been made, the annihilation component being dominant at this energy. We find that the energy dependence of inclusive cross sections for ϱ0 production inpp interactions and$\bar pp$ non-annihilations shows a type of scaling behaviour previously reported for ϕ, ψ, ψ′ and ϒ production inpp interactions.Δ++, ϱ0 andK*± production are studied in terms of Feynmanx,y* andpT2. For the vector mesons we compare they* andx dependences with the predictions of simple quark models.

INCLUSIVE SIGMA+- (1385) PRODUCTION IN anti-p p INTERACTIONS AT 12-GeV/c

Inclusive production of∑±(1385) resonances is studied in$\bar pp$ interactions at 12 GeV/c. The cross sections for∑+(1385)+cc and∑− are determined to be 251±38 μb and 123±30 μb, respectively. The inclusive spectra are presented as a function of Feynman x, c.m. rapidity and the squared transverse momentumpT2. Significant differences with the correspondingpp data are found in the longitudinal momentum distributions. The qualitative features of the production can be explained by simple quark ideas.

The reactions p p → K ∗ (890) X , p p →Σ ± (1385) X and p p → S ∗ (993) X at 12 GeV/ c incident momentum have been studied using 19 000 events with a visible V 0 decay in BEBC. Inclusive production cross sections of these resonances as a function of transverse momentum and rapidity are presented. The contribution of annihilation to the production of the K ∗ (890) is investigated from a comparison with the corresponding pp data.
