Abstract

The past eight years have seen a tremendous number of
interesting physics results obtained using data taken above the $\Upsilon(4S)$ by the Belle Collaboration, and in this talk, several of these results are summarized, with a focus on recent measurements of several cross-sections: $e^{+}e^{-}\to b\bar{b}$, $e^{+}e^{-}\to\pi^{+}\pi^{-}\Upsilon(nS)$, and $e^{+}e^{-}\to\pi^{+}\pi^{-} h_b(nP)$, as a function of $\sqrt{s}$ from approximately 10.6 to 11.0 $GeV$. In addition, results of the study of $e^{+}e^{-}\to \left(BB^{*}\right)^{\pm}\pi^{\mp}$ at $\Upsilon(5S)$ are also described.
