摘要：

We present a direct measurement of A(c) = 2 upsilon(c)a(c)/(upsilon(c)(2) + a(c)(2)) from the left-right forward-backward asymmetry of D*(+) and D+ mesons in Z(0) events produced with the longitudinally polarized SLAG Linear Collider beam. These Z(0) --> <c(c)over bar> events are tagged on the basis of event kinematics and decay topology from a sample of hadronic Z(0) decays recorded by the SLAG Large Detector. We measure A(c)(0) = 0.73 +/- 0.22(stat) +/- 0.10(syst).
