Production of the D-wave $b\bar{b}$ states

Abstract

The first and second families of D-wave $b\bar{b}$ quarkonium states are expected to have masses near 10.16 and 10.44 GeV/$c^2$. The accuracy of these predictions is discussed, and the prospects of two methods for producing these states in electron-positron collisions are updated. Direct scans in the $e^{+}{e}^{-}$ center-of-mass can give rise to the ${}^3{D}_1$ states. The $1^3{D}_J$ states have also been searched for in the electromagnetic cascades from $\text{ups}(3S)\to \gamma {\chi }_b^{\prime }\to \gamma {\gamma }^3{D}_J$. The sample of $\text{ups}(3S)$ decays required to definitively observe the $1^3{D}_J$ states is found to be only somewhat greater than the present world's total.
