Abstract

Reconstruction of charged D^*'s produced inclusively in e⁺e-. annihilation at CM energies near 34.4 GeV is accomplished in the decay modes D*⁺→D⁰π⁺→K^-gp⁺π⁰π⁺ and D*⁺→D⁰π⁺→ K^-gp⁺π^-π⁺π⁺ and their charge conjugates. Using these and previously reported D*⁺→D⁰π⁺→K^-gp⁺π⁺ and D*⁺→D⁰π⁺→ K^-gp⁺π⁺ + missing π⁰ channels we present evidence for hard gluon bremsstrahlung from charm quarks and show that the ratio of the quark-gluon coupling constant of charm quarks to the coupling constant obtained in the average hadronic event, α_s ^c α_rms = 100 ± 0.20 ± 1.20. Our result provides evidence that the quark-gluon coupling constant is independent of flavor.
