Abstract
Charm production in two-photon collisions has been measured at LEP for center-of-mass energies of se+e−=183–189 GeV using the ALEPH detector. Charm events have been detected via muons from semi-leptonic decays and via inclusive D* production. Preliminary results are presented. The total cross section σ(e+e−→e+e−cc) has been measured. The relative fractions of the contributing processes have been determined for the acceptance range of D* mesons. Differential D* cross sections in the transverse momentum and the pseudorapidity of the D*’s have been measured and compared to NLO QCD calculations.
