Abstract

The inclusive cross section for the production of charmed D∗± mesons in two-photon processes is measured with the AMY detector at the TRISTAN e+e− collider. D∗± mesons are identified from the distribution of charged-particle transverse momenta relative to the jet axis. A data sample corresponding to an integrated luminosity of 176 pb−1 at a center-of-mass energy of 58 GeV is used to determine a cross section σ(e+e− → e+e−D∗±X) = 270 ± 49(stat) ± 38(syst) pb. The results are compared with theoretical expectations based on the Vector Meson Dominance, direct quark-parton model, and resolved photon processes.
