This analysis, based on a sample of 170000 hadronic Z 0 decays, provides a measurement of the K ± and pp differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K ± and pp per hadronic event were found to be:N K = 2.26 ± 0.18 and N p = 1.07 ± 0.14. The positions ξ * of the maxima of the...
