Abstract

Using the VENUS detector at TRISTAN we have investigated the charm-quark production by detecting D *+ - mesons in the two-photon process of e + e t - collisions. The study has confirmed that the charm-quark production rate is larger than that predicted from direct cc̅ production alone. The distribution of the transverse momentum of the D *+ t- mesons and the forward energy flow associated with the D *+ - production suggest that the main part of the observed excess comes from the contribution of a resolved photon process.
