Abstract

The forward-backward asymmetry of charm quark production has been measured at an average of energy of 58.4 GeV with the VENUS detector at the TRISTAN e+e- collider. The charm quarks were identified through reconstruction of charged D* mesons using the mass difference between the D* and D0 mesons. The measured charge asymmetry, -0.49+.019 -0.17±0.04, is consistent with the prediction of the standard theory. The corresponding axial-vector coupling constant is 1.03+0.40 -0.35±0.07.
