# Charged and Identified Particles in the Hadronic Decay of W Bosons and in $e^{+} e^{-} \to q\overline{q}$ from 130 to 200 GeV

Abstract : Inclusive distributions of charged particles in hadronic Wdecays are experimentally investigated using the statisticscollected by the DELPHI experiment at LEP during 1997, 1998and 1999, at centre-of-mass energies from 183 to around 200 GeV.The possible effects of interconnection betweenthe hadronic decays of two Ws are not observed.Measurements of the average multiplicity for charged and identified particles in q$\bar{\mathrm q}$ and WW events at centre-of-mass energies from 130 to 200 GeV and in W decays are presented.The results on the average multiplicity of identified particlesand on the position $\xi^*$ of the maximum of the maximum of$\xi_p = -\mathrm{log} (\frac{2p}{\sqrt{s}})$distribution are compared with predictionsof JETSET and MLLA calculations.
