Inclusive charged hadron production, e(+)e(-) --> e(+)e(-)h(+/-)X, is studied using 414 pb(-1) of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 202 GeV. Single particle inclusive differential cross sections are measured as a function of the particle transverse momentum, p(t), and pseudo-rapidity, eta. For p(1) less than or equal to 1.5 GeV, the data are well described by an exponential, typical of soft hadronic processes. For higher p(1), the onset of perturbative QCD processes is observed. The pi(+/-) production cross section for p(t) > 5 GeV is much higher than the NLO QCD predictions. (C) 2003 Elsevier Science B.V. All rights reserved.
