Abstract

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, pt , and pseudo-rapidity, η. For p_t≤ 1.5 GeV, the data are well described by an exponential, typical of soft hadronic processes. For higher p_t , the onset of perturbative QCD processes is observed. The π ^±production cross section for p_t > 5 GeV is much higher than the NLO QCD predictions.
