Inclusive $\rho^0$, $K^*$+- (892) and F Production in $\bar{p} p$ Interactions at 12-{GeV}/$c$

Karimaki, V. ; Kinnunen, R. ; Korkea-aho, M. ; et al.

Inspire Record 164811 DOI 10.17182/hepdata.14087

Inclusive production of ϱ0,K*±(892), andf is studied in\(\bar p\)p interactions at 12 GeV/c. The inclusive cross sections for ϱ0,K*±(892), andf are found to be 6.7±0.3 mb, 1.0±0.2 mb, and 1.4±0.3 mb, respectively. The differential cross sections are presented as a function of c.m. rapidity, Feynmanx and square of the transverse momentumpT2. Comparison with the correspondingpp data shows some interesting differences which can be attributed to the\(\bar p\)p annihilation. The results are compared with the predictions of the quark fusion model.

Inclusive Production of $K^*$ (892) and $\Sigma$ (1385) in $\bar{p} p$ Interactions at 3.6-{GeV}/$c$ and a Test of Factorization Hypothesis

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 PRODUCTION OF K*+- (890) AND SIGMA+- (1385) RESONANCES IN ANTI-P P INTERACTIONS AT 14.75-GEV/C

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.

Inclusive Production of Vector and Tensor Mesons in anti-Proton-Proton Annihilation and Nonannihilation Interactions at 9.1-GeV/c

The LIVERPOOL-STOCKHOLM collaboration Markytan, M. ; Johnson, P. ; Mason, P. ; et al.
Nucl.Phys.B 143 (1978) 263-284, 1978.
Inspire Record 136559 DOI 10.17182/hepdata.8198

Cross sections have been determined for the inclusive production of vector (ϱ 0 , ω, K ∗ ) and tensor (f, A 2 ± ) mesons in p p reactions at 9.1 GeV/c for both annihilation and non-annihilation processes. Distributions in the Feynman variable x and transverse momentum squared, p T 2 , have been examined for the ϱ 0 , ω and f mesons. The slopes for p T 2 appear to be exponential and decrease with increasing particle mass for both annihilation and non-annihilation reactions, furthermore the slopes have consistently higher values for non-annihilation reactions. Comparisons with other data indicate that the ratio ϱ 0 / π − is independent of antiproton momentum in annihilation processes.
