抄録

We report on a measurement of the mean charged-particle multiplicity of jets in dijet events with dijet masses in the range 80-630 GeV/c2, produced at the Tevatron in pp̄ collisions with √s = 1.8 TeV and recorded by the Collider Detector at Fermilab. The data are fit to perturbative-QCD calculations carried out in the framework of the modified leading log approximation and the hypothesis of local parton-hadron duality. The fit yields values for two parameters in that framework: the ratio of parton multiplicities in gluon and quark jets, γ≡Ng-jet partons/Nq-jet partons = 1.7±0.3, and the ratio of the number of charged hadrons to the number of partons in a jet, Kcharged LPHD≡Ncharged hadrons/Npartons = 0.57±0.11.
