Description

We report first measurements of e+e-→D(*)+D(*)- processes far above threshold. The cross sections for e+e-→DT*+DL*- 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-→DL*+DL*-, e+e-→D+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
