Production of mesons with new flavor in $e^{+}{e}^{-}$ collisions

Cross sections for production of $B\overline{B}$, $\overline{B}{B}^{*}+{\overline{B}}^{*}B$, and $B^{*}{\overline{B}}^{*}$ mesons (carrying $b$-quark quantum numbers) in $e^{+}{e}^{-}$ annihilation are estimated and differential cross sections are evaluated. The cross sections for $e^{+}{e}^{-}\to e^{+}{e}^{-}{\eta }_b$, $e^{+}{e}^{-}\to e^{+}{e}^{-}{\chi }_b$, and $e^{+}{e}^{-}\to e^{+}{e}^{-}B\overline{B}$ are computed in the equivalent-photon approximation.
