TL;DR: Measurements of the e/sup +/e/sup -/ cross section above BB-bar threshold are reported and average charged multiplicities and inclusive lepton yields are presented.
Abstract: Measurements of the ${e}^{+}{e}^{\ensuremath{-}}$ cross section above $B\overline{B}$ threshold are reported. Structures are observed which could be the $\ensuremath{\Upsilon}(5S)$ and $\ensuremath{\Upsilon}(6S)$ resonances. The masses and widths are given and compared with various potential-model predictions. Average charged multiplicities and inclusive lepton yields are also presented.

TL;DR: The momentum distribution of the psi mesons suggests a significant fraction of two-body decays, and the inclusive branching ratio for B..-->..psiX is measured to be (1.10 +- 0.21 - 0.23)%.
Abstract: We have measured the inclusive branching ratio for B..-->..psiX to be (1.10 +- 0.21 +- 0.23)%. The momentum distribution of the psi mesons suggests a significant fraction of two-body decays.

TL;DR: The decay B-bar /sup 0/..-->..D/sup asterisk+/rho/sup -/ has been observed and the branching ratio is found to be (8.1 +- 2.9/sub -2.4//sup +5.9/)%. The result is compared with theoretical predictions as mentioned in this paper.
