Inclusive D∗± production in two-photon collisions at LEP
2002
Abstract Inclusive D ∗± production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb −1 of data collected at centre-of-mass energies from 183 to 209 GeV. Differential cross sections are determined as functions of the transverse momentum and pseudorapidity of the D ∗± mesons in the kinematic region 1 GeV P T η | σ( e + e − →e + e − D ∗± X ) in this kinematical region is measured and the σ( e + e − →e + e − c c X ) cross section is derived. The measurements are compared with next-to-leading order perturbative QCD calculations.
