The DELPHI experiment at LEP uses Ring Imaging Cherenkov detectors for particle identification. The good understanding of the RICH detectors allows the identification of charged pions, kaons and protons, covering the full momentum range from 0.7 < p < 45.6GeV/c. The ϱ, K±, p and pÌ normalised production rates, their differential cross sections, multiplicities and the maxima ξ*pof_the ξp= ln (1/Xp) distributions are measured for three event samples Z0â qqÌ, Z0â bbÌ, Z0â uÅ«, ddÌ, ssÌ, selected from â¼ 1 400 000 Z0decays collected by DELPHI in 1994. The results are compared to the predictions of the JETSET string fragmentation model and the HERWIG cluster fragmentation model. The Modified Leading Logarithm Approximation with Local Parton-Hadron Duality is tested. The ξ*pdependence on the primary quark flavour is investigated and quantified for the different particle distributions. The ϱ, K±, p and pÌ multiplicities are measured with precisions from ±4% to ±6%. Forche Z0â qqÌ, and Z0â bbÌ, event samples, these improve on previous measurements. The ϱ, K±, p and pÌ multiplicities for Z0â uÅ«, ddÌ, ssÌ are presented for the first time.
