Abstract

We present a direct measurement of the parity-violation parameter A_c in the coupling of the Z⁰ to c quarks with the SLD detector. The measurement is based on a sample of 530 k hadronic Z⁰ 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 D⁰ mesons, and the soft pions (π_s) produced in the decay of D*⁺→D⁰π_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.

N2 - We present a direct measurement of the parity-violation parameter Ac in the coupling of the Z0 to c quarks with the SLD detector. The measurement is based on a sample of 530 k hadronic Z0 decays, produced with a mean electron-beam polarization of |Pe| = 73%. The tagging of c-quark events is performed using two methods: the exclusive reconstruction of D*+, D+, and D0 mesons, and the soft pions (πs) produced in the decay of D*+→D0πs+. 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 Ac= 0.688 ± 0.041.
