| Résumé : | This analysis, based on a sample of 170000 hadronic Z0 decays, provides a measurement of the K± and p/p̄ differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K± and p/p̄ per hadronic event were found to be: NK = 2.26 ± 0.18 and Np = 1.07 ± 0.14. The positions ξ* of the maxima of the differential cross sections as a function of ξ = In(1/xp) for K± and p/p̄ were determined to be 2.63 ± 0.07 and 2.96 ± 0.16 respectively. A comparison of the ξ* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation with Local Parton Hadron Duality model has been performed. The measured ξ* position as a function of the hadron mass, after corrections due to particle decays, is in agreement with the model calculation. |
