Inclusive $\pi^0$ and $\eta$ Meson Production in Electron Positron Interactions at $\sqrt{s}=10$-{GeV}

The ARGUS collaboration Albrecht, H. ; Glaser, R. ; Harder, G. ; et al.

Inspire Record 278933 DOI 10.17182/hepdata.15301

We report on a high statistics study of π0 and η production in continuum events and in direct decays of the Γ(1S) and Γ(2S) resonances. The measured production rates per event are\(\left\langle {n_{\pi ^0 } } \right\rangle\)=3.22 ± 0.07 ± 0.31 (3.97 ± 0.23 ± 0.38) and 〈nη〉=0.19 ± 0.04 ± 0.04 (0.40 ± 0.14 ± 0.09) for continuum events (direct Γ(1S) decays).

Inclusive $\phi$ Meson Production in Electron - Positron Interactions in the Energy Region of the $\Upsilon$ Resonances

Inspire Record 262551 DOI 10.17182/hepdata.15528

We report on a high precision measurement of ϕ-meson production in continuum events and in direct decays of the Υ(1S)- and Υ(2S)-mesons. The ratio of the total production rate of ϕ-mesons in direct Υ(1S)- and Υ(2S)-decays over that in continuum events is 1.32±0.08±0.09 and 1.07±0.13±0.11 respectively. This is compatible with the corresponding ratio obtained for lighter mesons, but is appreciably smaller than the relative baryon production rate.

NEUTRAL STRANGE PARTICLE PRODUCTION IN ANTI-NEUTRINOS INDUCED NEUTRAL CURRENT INTERACTIONS

Phys.Lett.B 140 (1984) 127-129, 1984.
Inspire Record 200832 DOI 10.17182/hepdata.10145

The study of neutral strange particle production in antineutrino-induced neutral current interactions is presented. The total multiplicity of neutral strange particles and the K 0 multiplicity in the current fragmentation region ( z >0.3) are used to estimate in two ways the coupling strength of the weak neutral current to the strange quark.

Quark Jets from Antineutrino Interactions II: Inclusive Particle Spectra and Multiplicities in the Quark Jets

Ammosov, V.V. ; Denisov, A.G. ; Gapienko, G.S. ; et al.
Nucl.Phys.B 203 (1982) 1-15, 1982.
Inspire Record 156746 DOI 10.17182/hepdata.41254

We present results on inclusive particle production in the antineutrino charged current induced hadron jets observed in the Fermilab 15 ft bubble chamber. Fractional energy distributions, particle ratios and average multiplicities of the hadrons in the jets are measured. Ratios between the inclusive production rates of different mesons in the jets are studied to seek evidence for the d-quark origin of the observed hadrons. Good over-all agreement with the hypothesis of d-quark fragmentation with universal fragmentation functions obeying isospin systematics is established.
