Abstract

We have studied the production of charged D^* mesons in e⁺ e^- annihilation at an average center-of-mass energy of 58.0 GeV. Charged D^* mesons were identified using two independent methods; the mass-difference method and the detection of the low transverse-momentum pion. The forward-backward asymmetry of the charm quark production was measured to be A_c= -0.61±0.13(stat.)±0.08(syst.). The cross section of inclusive D^* production was found to be σ(e⁺ e^-→D^{* ±}+X) = 24.5 ± 5.3 (stat.)±3.0(syst.) pb. If we assume the standard model prediction for the charm quark production, we obtain the branching ratio for the charm quark to produce a charged D^* meson to be Br(c→D^*+ + X) = (22±5(stat.)±3(syst.))%.
