Abstract

We report the first measurement of the inclusive e+e→bb¯→Ds±X and e+e→bb¯→ D0/D¯0X cross sections in the energy range from 10.63 to 11.02 GeV. Based on these results, we determine σ(e+e→Bs0s0X) and σ(e+e→BB¯X) in the same energy range. We measure the fraction of Bs0 events at Υ(10860) to be fs = (22.0−2.1+2.0)%. We determine also the ratio of the Bs0 inclusive branching fractions B(Bs0→ D0/D¯0X)/B(Bs0→Ds±X) = 0.416 ± 0.018 ± 0.092. The results are obtained using the data collected with the Belle detector at the KEKB asymmetric-energy e+e collider.
