Measurement of A{sub c} with charmed mesons at SLD
- SLAC
We present a direct measurement of the parity-violation parameter A{sub c}. The measurement is based on 550k Z{sup 0} decays collected by the SLD detector. The mean electron-beam polarization is |P{sub e}| = 73%. The tagging of c-quark events was performed using two methods: The exclusive reconstruction of D*{sup +}, D{sup +}, and D{sup 0} mesons, and the inclusive P{sub T} spectrum of soft-pions ({pi}{sub s}) in the decay of D*{sup +} {yields} D{sup 0}{pi}{sub s}{sup +}. The results of these two methods are combined to give A{sub c} = 0.688 {+-} 0.035(stat.) {+-} 0.025(sys.) (preliminary).
