Measurement of eta production in two and three jet events from hadronic Z decays at LEP

The L3 collaboration Acciarri, M. ; Adam, A. ; Adriani, O. ; et al.

Phys.Lett.B 371 (1996) 126-136, 1996.

Inspire Record 404602 DOI 10.17182/hepdata.48038

The inclusive production of η mesons has been studied using 1.6 million hadronic Z decays collected with the L3 detector. The η multiplicity per event, the multiplicity for two-jet and three-jet events separately, and the multiplicity in each jet have been measured and compared with the predictions of different Monte Carlo programs. The momentum spectra of η in each jet have also been measured. We observe that the measured η momentum spectrum in quark-enriched jets agrees well with the Monte Carlo prediction while in gluon-enriched jets it is harder than that predicted by the Monte Carlo models.

Rescattering probed by the emission of slow target associated particles in high-energy heavy ion interactions

The EMU01 collaboration Adamovich, M.I ; Aggarwal, M.M ; Alexandrov, Y.A ; et al.

Phys.Lett.B 363 (1995) 230-236, 1995.

Inspire Record 406952 DOI 10.17182/hepdata.28438

In this letter the distribution of slow target associated particles emitted in Au + Emulsion interactions at 11.6 A GeV/ c is studied. The three models RQMD, FRITIOF and VENUS are used for comparisons and especially their treatment of rescattering is investigated.

Neutral strange particle production in anti-neutrino - neon charged current interactions

The WA59 collaboration Willocq, S. ; Marage, P. ; Aderholz, M. ; et al.

Z.Phys.C 53 (1992) 207-218, 1992.

Inspire Record 319235 DOI 10.17182/hepdata.14768

Neutral strange particle production in$\bar v$ Ne charged current interactions is studied using the bubble chamber BEBC, exposed to the CERN SPS antineutrino wide band beam. From a sample of 1191 neutral strange particles, the inclusive production rates are determined to be (15.7±0.8)% forK0 mesons, (8.2±0.5)% for Λ, (0.4±0.2)% for$\bar \Lambda $ and (0.6±0.3)% for Σ0 hyperons. The inclusive production properties ofK0 mesons and Λ hyperons are investigated. The Λ hyperons are found to be polarized in the production plane.

Inclusive production of vector mesons in pi+ p interactions at 250-GeV/c

The EHS/NA22 collaboration Agababyan, N.M. ; Ajinenko, I.V. ; Belokopytov, Yu. A. ; et al.

Z.Phys.C 46 (1990) 387-395, 1990.

Inspire Record 301243 DOI 10.17182/hepdata.15240

We report on a study of ρ0, ρ+, ω,$\bar K^{*0} (892)$ andK*0 (892) inclusive production in π+p interactions at 250 GeV/c, for ρ+,$\bar K^{*0} (892)$ for the first time in a π+p experiment. The data are compared withK+p data in the same experiment, with results of other experiments and with quark-parton models. Interesting differences are found between ρ+,0 and ω production.

Limiting Fragmentation in Oxygen Induced Emulsion Interactions at 14.6-a/{GeV}, 60-a/{GeV} and 200-a/{GeV}

The EMU01 collaboration Adamovich, M.I. ; Aggarwal, M.M. ; Arora, R. ; et al.

Phys.Rev.Lett. 62 (1989) 2801, 1989.

Inspire Record 268021 DOI 10.17182/hepdata.20041

Pseudorapidity distributions of relativistic singly charged particles in oxygen-induced emulsion interactions at 14.6, 60, and 200 GeV/nucleon are studied. Limiting fragmentation behavior is observed in both the target and projectile fragmentation regions for a central as well as for a minimum-bias sample. Comparisons with the fritiof model reveal that the picture of fragmenting strings successfully describes the observed data.
