Abstract
Inclusive distributions of charged particles in hadronic W decays
are experimentally investigated using the statistics
collected by the DELPHI experiment at LEP during 1997, 1998 and 1999,
at centre-of-mass energies from 183 to around 200 GeV.
The possible effects of interconnection between
the hadronic decays of two Ws are not observed.
Measurements of the average multiplicity for charged and identified
particles in 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 particles
and on the position
of the maximum of the
distribution are compared with predictions
of JETSET and MLLA calculations.
