摘要：

This analysis, based on a sample of 170000 hadronic Z(0) decays, provides a measurement of the K-+/- and p/($) over bar p differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K-+/- and pip per hadronic event were found to be: N-K = 2.26 +/- 0.18 and N-p = 1.07 +/- 0.14. The positions xi* of the maxima of the differential cross sections as a function of xi = In(1/x(p)) for K-+/- and p/($) over bar p were determined to be 2.63 +/- 0.07 and 2.96 +/- 0.16 respectively. A comparison of the xi* 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 xi* position as a function of the hadron mass, after corrections due to particle decays, is in agreement with the model calculation.
