The JADE collaboration Bartel, W. ; Cords, D. ; Dittmann, P. ; et al.
Phys.Lett.B 104 (1981) 325-329, 1981.
Inspire Record 166363 DOI 10.17182/hepdata.31062

Data on p and Λ production by e + e − -annihilation at CM energies between 30 and 36 GeV are presented. Indication for an angular anticorrelation in events with baryon-antibaryon pairs is seen.

Charged Current Events with Neutral Strange Particles in High Energy Antineutrino Interactions

Ammosov, V.V. ; Denisov, A.G. ; Ermolov, P.F. ; et al.
Nucl.Phys.B 177 (1981) 365-381, 1981.
Inspire Record 153884 DOI 10.17182/hepdata.42576

The results of a study of strange particle production in charged current $\bar{\nu}_{\mu} N$ interactions in the Fermilab 15 ft bubble chamber filled with a heavy $Ne-H_2$ mixture are presented. Production rates and average multiplicities of $K^0$'s and Λ's as functions of W 2 and Q 2 are given. The experimental data agree well with the quark-parton model predictions if a yield of 0.06 ± 0.02 of $K^0$'s and Λ's from charm production is included. Upper limits for D-meson production are given and the shape of the charmed quark fragmentation function is discussed. Inclusive production of the K ∗ (890) and Σ(1385) resonances is measured and it is shown that only about 5% of the K 0 mesons and Λ hyperons results from resonance decays. Relative production rates of neutral strange particles on proton and neutron targets are studied.

Evidence for a Resonant Behavior in e+ e- Annihilation Into Hadrons, Around 1820-MeV, at ADONE

Bacci, C. ; Baldini-Celio, R. ; Capon, G. ; et al.
Phys.Lett.B 68 (1977) 393-396, 1977.
Inspire Record 119881 DOI 10.17182/hepdata.27562

Multihadron production has been measured at the Adone e + e − storage ring in the c.m. energy region 1600 ÷ 1900 MeV. A resonant behaviour is observed, centered at 1819 ± 5 (±2) MeV, with a width of 24 ± 5 (±4) MeV. This effect is observed only in the events with 3 or 4 charged particles together with photons, but not in those without photons.

A Measurement of the Cross-Section of the Reaction p p --> n Delta++ (1232) at ISR Energies

Kwak, N. ; Nagy, E. ; Regler, M. ; et al.
Phys.Lett.B 62 (1976) 359-362, 1976.
Inspire Record 108757 DOI 10.17182/hepdata.27678

A measurement of the cross section of the charge-exchange reaction pp→ Δ ++ (1232)n at √ s = 23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependence continues to follow a power law p lab − n with n = 1.94 ± 0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.
