Measurement of Ac with charmed mesons at SLD
Description
We present a direct measurement of the parity-violation parameter Ac. The measurement is based on 550k Z0 decays collected by the SLD detector. The mean electron-beam polarization is |Pe| = 73%. The tagging of c-quark events was performed using two methods: The exclusive reconstruction of D*+, D+, and D0 mesons, and the inclusive PT spectrum of soft-pions (πs) in the decay of D*+ → D0πs+. The results of these two methods are combined to give Ac = 0.688 ± 0.035(stat.) ± 0.025(sys.) (preliminary)
