Abstract
The inclusive production rates of pi+/-, K+/- and ppBAR in Z0 decays h ave been measured with the OPAL detector at LEP. Using the energy loss measurement in the jet chamber, the momentum range up to the beam ene rgy (45.6 GeV/c) has been covered. Differential cross sections and tot al particle yields are given. Comparisons of the inclusive momentum sp ectra and the total rates with predictions of the JETSET and the HERWI G Monte Carlo model are presented. The total single rates are found to be 17.05+/-0.43 pi+/-, 2.42+/-0.13K+/- and 0.92+/-0.11 ppBAR per hadr onic event. Predictions of JETSET for cross sections and total rates a gree very well for pi+/-; however, for momenta greater than 4 GeV/c, K +/- rates are underestimated and ppBAR rates are overestimated. Combi ned with data of other particle species there is evidence that the pea k positions in the xi=1n(1/x(p)) distributions show a different mass d ependence for mesons and baryons. However, both JETSET and HERWIG Mont e Carlo predictions agree with the observed data.
