Measurement of the nergy dependence of the charged multiplicity in deep inelastic scattering with ZEUS at HERA 

The charged multiplicity distributions and the mean charged
multiplicity were investigated in inclusive neutral current deep
inelastic ep scattering with the ZEUS detector at HERA using an
integrated luminosity of 38.6 pb-1. The measurements were performed in
the current region of the Breit frame, as well as in the current
fragmentation region of the hadronic centre-of-mass frame. The
KNO-scaling properties of the data were investigated and the energy
dependence was studied using different energy scales. The data are
compared to results obtained in e+e- collisions and to previous DIS
measurements as well as to leading-logarithm parton-shower Monte Carlo
predictions.
