Abstract

The production of D* and D mesons has been studied in e+e− annihilations at √s = 29GeV. The data, corresponding to an integrated luminosity of 300 pb−1, were obtained using the HRS detector at PEP. The cross section is measured to be R (D0 + D+) = 2.40±0.35 and we determine the electroweak asymmetry to be −9.9 ± 2.7%, which corresponds to an axial vector coupling constant product gegc = 0.26 ± 0.07.
