Inclusive charged hadron distributions as obtained from the DELPHI measurem
ents at 130, 136, 161, 172 and 183 GeV are presented as a function of the v
ariables rapidity, xi(p), p and transversal momenta. Data are compared with
event generators and with MLLA calculations, in order to examine the hypot
hesis of local parton hadron duality. The differential momentum spectra sho
w an indication for coherence effects in the production of soft particles.
The relation between the energy dependence of the charged multiplicity and
the rapidity distribution is examined. (C) 1999 Elsevier Science B.V. All r
