S. Aid et al., CHARGED-PARTICLE MULTIPLICITIES IN DEEP-INELASTIC SCATTERING AT HERA, Zeitschrift fur Physik. C, Particles and fields, 72(4), 1996, pp. 573-592
Using the H1 detector at HERA, charged particle multiplicity distribut
ions in deep inelastic e(+)p scattering have been measured over a larg
e kinematical region. The evolution with W and Q(2) of the multiplicit
y distribution and of the multiplicity moments in pseudorapidity domai
ns of varying size is studied in the current fragmentation region of t
he hadronic centre-of-mass frame. The results are compared with data f
rom fixed target lepton-nucleon interactions, e(+)e(-) annihilations a
nd hadron-hadron collisions as well as with expectations from QCD base
d parton models. Fits to the Negative Binomial and Lognormal distribut
ions are resented.
