Measurement Of D*(+/-) Production In Two-Photon Processes At Tristan

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 sigma(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.
