On the origin of approximate KNO scaling in e+e- annihilation
Zeitschrift für Physik C Particles and Fields 31:2 (1986) 327-331
Abstract:
KNO scaling of the multiplicity distribution in hadronic final states was originally derived as a consequence of Feynman scaling. We show that in iterative models of hadron production in jets, incorporating Feynman scaling, KNO scaling obtains only in the limit when the width of the multiplicity distribution tends to zero. Within the context of the models currently employed to describe e+e- annihilation into hadrons, the apparent KNO scaling observed is an accidental consequence of effects which violate Feynman scaling. © 1986 Springer-Verlag.Inclusive π0 production by e+e- annihilation at 34.6 GeV center of mass energy

Abstract:
The cross section for the process e+e-→π0+ anything has been measured at an average center of mass energy of 34.6 GeV for π0 energies between 0.7 and 17 GeV. The angular distribution for π0 energies larger than 2 GeV is of the form dσ/dΩ∼1+Acos2θ, with A=1.2±0.5. The ratio of π0 to π± production in the measured energy range is 2σ(π0)/(σ(π+)+σ(π-))=1.13±0.18 The form of the differential cross sections agrees within the errors. The mean π0 multiplicity is 5.8±0.9. © 1986 Springer-Verlag.Physics Briefing Book : Input for the European Strategy for Particle Physics Update 2020
