Particle Composition in Hadronic Jets in e+e- Annihilation

The production of neutral kaons in Z0 decays and their Bose-Einstein correlations

“…The higher value for the ratio of strange vector mesons to vector plus pseudoscalar mesons is derived from the mean value and the errors given in Ref. [33], while the lower value was the one presented by this experiment in Ref. [34].…”

“…For example, the Λ to h − ratio is approximately 0.35 at p T of 2 GeV/c. Data from e + e − collisions and calculations from string fragmentation models, however, indicate that although the baryon to meson ratio from quark and gluon fragmentation increases as a function of Feynman x, the ratio never exceeds 0.2 [33]. As mentioned above, a natural explanation for the increase at high p T would be a large collective radial flow at RHIC [26,29].…”

Momentum kick model description of the near-side ridge and jet quenching

“…Rapidity distributions in the form of a plateau have been known in QCD particle production processes both experimentally and theoretically. Experimental evidence for a plateau rapidity distributions along the sphericity axis or the thrust axis has been found in π ± production in e + -e − annihilation [36,37,38,39,40,41]. The rapidity distributions for K ± production also show a plateau structure with a depression in an extended region around y ∼ 0.…”
