| Résumé : | The inclusive production of D*± mesons in two-photon collisions is measured with the ALEPH detector at e+e- centre-of-mass energies from 183 GeV to 209 GeV. A total of 360±27 D*± meson events are observed from an integrated luminosity of 699 pb-1. Contributions from direct and single-resolved processes are separated using the ratio of the transverse momentum ptD*± of the D*± to the visible invariant mass Wvis of the event. Differential cross sections of D*= production as functions of ptD*± and the pseudorapidity |
