Abstract

Charged particle production in deep-inelastic ep scattering is measured with the H1 detector at HERA. The kinematic range of the analysis covers low photon virtualities, 5 < Q² < 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 particle densities are measured as a function of pseudorapidity (eta^*) and transverse momentum (p_T^*) in the range 0< η^* < 5 and 0< p_T^* < 10 GeV differentially in x and Q². The data are compared to predictions from different Monte Carlo generators implementing various options for hadronisation and parton evolutions.
