Abstract
The reactions e+e − →e+e − ?0 X and e+e − →e+e − KS0 X are studied using data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 202 GeV. Inclusive differential cross sections are measured as a function of the particle transverse momentum pt and the pseudo-rapidity. For pt≤1.5 GeV, the π0 and KS0 differential cross sections are described by an exponential, typical of soft hadronic processes. For pt≤1.5 GeV, the cross sections show the presence of perturbative QCD processes, described by a power-law. The data are compared to Monte Carlo predictions and to NLO QCD calculations.
