Abstract

We report first measurements of e⁺e^- → D ^(*)+ D^(*)- processes far above threshold. The cross sections for e⁺ e^- → D_T* ⁺ D_T*^- and e⁺ e^- → D⁺ D_T*^- at √s ≃ 10.6 GeV/c² are measured to be 0.55 ± 0.03 ± 0.05 and 0.62 ± 0.03 ± 0.06 pb, respectively. We set upper limits on the cross sections for e⁺e^- → D_T*⁺ D_T*^-, e⁺ e^- → D _L*⁺ D_L*^-, e⁺ e^- → D_L*⁺ D_L* ^-, and e⁺ e^- → D⁺ D _-* processes. The analysis is based on 88.9 fb^-1 of data collected by the Belle experiment at the KEKB e⁺e^- asymmetric collider.

N2 - We report first measurements of e+e- → D (*)+ D(*)- processes far above threshold. The cross sections for e+ e- → DT* + DT*- and e+ e- → D+ DT*- at √s ≃ 10.6 GeV/c2 are measured to be 0.55 ± 0.03 ± 0.05 and 0.62 ± 0.03 ± 0.06 pb, respectively. We set upper limits on the cross sections for e+e- → DT*+ DT*-, e+ e- → D L*+ DL*-, e+ e- → DL*+ DL* -, and e+ e- → D+ D -* processes. The analysis is based on 88.9 fb-1 of data collected by the Belle experiment at the KEKB e+e- asymmetric collider.
