Abstract: We report the first measurement of the inclusive e + e − → $$ b\\overline{b} $$ b b ¯ → $$ {D}_s^{\\pm } $$ D s ± X and e + e − → $$ b\\overline{b} $$ b b ¯ → D 0 / $$ {\\overline{D}}^0 $$ D ¯ 0 X cross sections in the energy range from 10 . 63 to 11 . 02 GeV. Based on these results, we determine σ ( e + e − → $$ {B}_s^0{\\overline{B}}_s^0 $$ B s 0 B ¯ s 0 X ) and σ ( e + e − → $$ B\\overline{B} $$ B B ¯ X ) in the same energy range. We measure the fraction of $$ {B}_s^0 $$ B s 0 events at Υ(10860) to be f s = ( $$ {22.0}_{-2.1}^{+2.0} $$ 22.0 − 2.1 + 2.0 )%. We determine also the ratio of the $$ {B}_s^0 $$ B s 0 inclusive branching fractions $$ \\mathcal{B} $$ B ( $$ {B}_s^0 $$ B s 0 → D 0 / $$ {\\overline{D}}^0 $$ D ¯ 0 X ) / $$ \\mathcal{B} $$ B ( $$ {B}_s^0 $$ B s 0 → $$ {D}_s^{\\pm } $$ D s ± 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.

Abstract: We measure the cross section of e + e − → η c J/ψ at the Υ( nS )( n = 1–5) on-resonance and 10.52 GeV off-resonance energy points using the full data s le collected by the Belle detector with an integrated luminosity of 955 fb − 1 . We also search for double charmonium production in e + e − → η c J/ψ via initial state radiation near the η c J/ψ threshold. No evident signal of the double charmonium state is found, but evidence for the e + e − → η c J/ψ process is found with a statistical significance greater than 3 . 3 σ near the η c J/ψ threshold. The average cross section near the threshold is measured and upper limits of cross sections are set for other regions.
