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