Enhancement of strange and multi-strange baryons and anti-baryons in S W interactions at 200-GeV/c.

The WA85 collaboration Antinori, F. ; Barnes, R.P. ; Bayes, A.C. ; et al.
Phys.Lett.B 447 (1999) 178-182, 1999.
Inspire Record 500180 DOI 10.17182/hepdata.28123

Strange and multistrange baryon production is expected to be enhanced in heavy ion interactions if a phase transition from hadronic matter to a Quark-Gluon Plasma takes place. The production yields of Λ s, Λ s, Ξ − s, and Ξ + s relative to the production of negative particles are presented for sulphur-tungsten interactions at 200 GeV/ c per nucleon. These production yields are compared to those produced in proton-tungsten interactions and the enhancements of strange and multistrange baryons and antibaryons are presented.

Measurement of the probability of gluon splitting into charmed quarks in hadronic Z decays

The L3 collaboration Acciarri, M. ; Achard, P. ; Adriani, O. ; et al.
Phys.Lett.B 476 (2000) 243-255, 2000.
Inspire Record 510061 DOI 10.17182/hepdata.49044

We have measured the probability, n(g->cc~), of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods have been applied to events with a three-jet topology. One method relies on tagging charmed hadrons by identifying a lepton in the lowest energy jet. The other method uses a neural network based on global event shape parameters. Combining both methods, we measure n(g->cc~)= [2.45 +/- 0.29 +/- 0.53]%.
