INCLUSIVE PRODUCTION OF NEUTRAL STRANGE PARTICLES IN ANTI-P P INTERACTIONS AT 70-GeV/c

Lemonne, J. ; Vanhomwegen, G. ; Wickens, J. ; et al.
Z.Phys.C 24 (1984) 103-110, 1984.
Inspire Record 207327 DOI 10.17182/hepdata.16319

The inclusive production ofKs0, Λ and\(\bar \Lambda \) particles is investigated in 70 GeV/c\(\bar pp\) interactions in an experiment performed at CERN using BEBC equipped with a TST. Differential cross-sections are studied and compared with corresponding data at surrounding energies. Differences withpp data obtained at the same energy allow an estimate of theKs0, production cross-section in annihilation processes. Evidence is also given for central\(\Lambda \bar \Lambda \) production.

CHARGED PARTICLE AND PI0 MULTIPLICITY DISTRIBUTIONS AND THE ANNIHILATION PROPERTIES OF ANTI-P P INTERACTIONS AT 70-GeV/c

Dumont, J.J. ; Lemonne, J. ; Vanhomwegen, G. ; et al.
Z.Phys.C 13 (1982) 1-9, 1982.
Inspire Record 179759 DOI 10.17182/hepdata.16433

The elastic and inelastic\(\bar p\)p cross sections at 70 GeV/c have been determined in an experiment performed at CERN using BEBC equipped with a TST. The topological cross sections were measured and the moments of the inelastic multiplicity distribution are 〈nc〉=6.16±0.09, 〈nc〉/D=2.04±0.05 andf2cc=2.97±0.03. The average number of Dalitz pairs per inelastic event is (3.12±0.09)×10−2. Assuming that these all arise from π0 decay the average π0 multiplicity is\(\langle n_{\pi ^0 } \rangle= 2.71 \pm 0.14\). The\(\bar p\)p−pp cross section differences lead to an annihilation cross section σA = 4.42±0.41 mb and the moments of the annihilation multiplicty distribution are 〈nA〉=8.0±0.3, 〈nA〉/D=2.5±0.2 andf2A−−=−1.4±0.3. An independent check of σA was made by investigating fast forward charged and neutral secondary interactions in the TST and in the surrounding neon-hydrogen mixture, and gives a value σA = 5.0±1.6 mb. The ratio of fast\(\bar n\) to\(\bar p\) production in non-annihilation interactions at 70 GeV/c is found to be 0.45±0.11.

Study of Inclusive Production of Boson Resonances in $\bar{p} p$ Interactions at 32-{GeV}/$c$

The inclusive production ofK*±(890), ρρ(770), ω0(780) andf0(1,270) mesons is studied in\(\bar pp\) experiment at 32GeV/c in the MIRABELLE bubble chamber by the analysis of (K0π±) 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(f0)=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.

CROSS-SECTIONS FOR EXCLUSIVE CHANNELS IN anti-p p REACTIONS AT 12-GeV/c

The Brussels-CERN-London-Mons-Orsay collaboration Casali, R. ; Anostolakis, A. ; Caso, C. ; et al.
Z.Phys.C 11 (1982) 273, 1982.
Inspire Record 167028 DOI 10.17182/hepdata.16434

The data obtained in an exposure of BEBC to an r.f. separated beam of antiprotons at 12 GeV/c are used to derive exclusive cross sections for reactions having one or more neutral strange particles in the final state. Particular attention is given to the estimation of the background. An upper limit of the cross section for the inclusive production of the charmed mesonD* is also given.

The cross sections of several exclusive reactions in p p interactions are given. In the channels p p → p p π + π − and p p → p p 2π + 2π − which dominate the interactions, the single and double diffractive dissociations are analysed and compared to the results obtained with K ± p interactions at the same energy, pp and p p interactions at other energies. The test of factorization at the p → p π + π − vertex is well verified. The process p p → Δ ++ Δ ++ is studied and the cross sections of Δ ++ , Δ ++ , ϱ 0 and f 0 production are also given.
