D*± production by e+e- annihilation near 34.4 GeV cm energy

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 produ...
