Abstract
D*± production via e+e-→D*±X has been measured at an average CM energy of 34.4 GeV. The D*± energy spectrum is hard, with a maximum near χ = 0.6. The size of the D* cross section, RD* = σ(e+e- → D*X) σμμ = 2.50 ± 0.64 ± 0.88 (assuming RD*0 = RD*+ ) indicates that a large fraction of charm quark production yields D* mesons. The D*± angular distribution exhibits a forward-backward asymmetry, A = -0.28 ± 0.13. This is consistent with that expected in the standard theory for weak neutral currents and leads to |gA c| = 0.89 ± 0.44 for the axial vector coupling of the charm quark.
