摘要：

The average charged track multiplicity and the normalised distribution of the scaled momentum, x(p), of charged final state hadrons are measured in deep-inelastic ep scattering at high Q(2) in the Breit frame of reference. The analysis covers the range of photon virtuality 100 < Q(2) < 20000 GeV2. Compared with previous results presented by HERA experiments this analysis has a significantly higher statistical precision and extends the phase space to higher Q(2) and to the full range of x(p). The results are compared with e(+)e(-) annihilation data and with various calculations based on perturbative QCD using different models of the hadronisation process.
