Measurement of Charged Particle Spectra in Deep-Inelastic ep Scattering at HERA

Charged particleproduction in deep-inelastic ep scattering is measured with the H1 detector at HERA. The kinematic range of the analysis covers low photon virtualities, 5 < Q(2) < 100 GeV2, and small values of Bjorken-x, 10(-4) < x < 10(-2). The analysis is performed in the hadronic centre-of-mass system. The charged particledensities are measured as a function of pseudorapidity(n(*)) and transverse momentum (p(T)(*)) in the range 0 < n(*) < 5 and 0 < p(T)(*) < 10 GeV in bins of x and Q(2). The data are compared to predictions from different Monte Carlo generators implementing various options for hadronisation and parton evolutions.
