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- collisions. The study has confirmed that the charm-quark production rate is larger than that predicted from direct cc̄ production alone. The distribution of the transverse momentum of the D*± 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.
