Measurement of A_c with Charmed Mesons at SLD

We present a direct measurement of the parity-violation parameter A(c) in the coupling of the Z(0) to c quarks with the SLD detector. The measurement is based on a sample of 530 k hadronic Z(0) decays, produced with a mean electron-beam polarization of \P(e)\ = 73%. The tagging of c-quark events is performed using two methods: the exclusive reconstruction of D*(+). D(+), and D(0) mesons, and the soft pions (pi (s)) produced in the decay of D*(+) --> D(0)pi (+)(s). The large background from D mesons produced in B hadron decays is separated efficiently from the signal using precision vertex information. The combination of these two methods yields A(c) = 0.688 +/- 0.041.
