| Abstract: | Inclusive momentum and energy spectra of neutral and charged D-mesons produced in e+e? annihilation at energies near 7 GeV are presented. The slope of the energy spectrum is similar to the charged pion spectrum at the same energy. The inclusive cross section σ(e+e?→ D or + anything) at 7 GeV is 4.8±1.3 nb. |
