The production of charged particles produced in Deep Inelastic Scattering (DIS) events at HERA has been studied using the ZEUS detector. Measurements have been made of the fragmentation variables xp and ln(1/xp)current region of the Breit frame of the interaction in the ranges 10 <Q2<5120 GeV2 and 0.6 10-3 < x < 0.25. Evidence is found for scaling violations in the scaled momentum, xp, as a function of Q2, and the data are shown to be well described by Next-to-Leading order calculations. The description of the ln(1/xp) distributions by the Modified Leading Log Approximation (MLLA) is studied, and its predictions for their evolution with energy are investigated. The data are compared with results from e+e- annihilation experiments.
