 note = {Measurements of open charm production in photon-photon collisions made with the AMY detector at TRISTAN are reported. Charmed hadrons were identified by detecting the high momentum muons or electrons from their semileptonic decays. The data sample corresponds to an integrated luminosity of 275 pb−1 at an average center of mass energy of 58 GeV. Results are presented in the form of cross sections of inclusive leptons from charm for both muons and electrons. The measured cross section is 1.8 standard deviations higher than theoretical predictions based on the direct and photon-gluon fusion process, where the mass of charm quark is assumed to be 1.6 GeV., 学位の種類: 博士（理学）. 報告番号: 甲第1162号. 学位記番号: 新大院博（理）甲第53号. 学位授与年月日: 平成8年3月21日, Physics Letters. 1995, B 363(4), 249-258., 新大院博（理）甲第53号},
