Results in $B_s$ physics and bottomonium spectroscopy using the Belle ${\rm Y}(5S)$ data

Abstract

The Belle experiment at KEK accumulated a $121.4{\mathrm{fb}}^{-1}$ sample of $e^{+}{e}^{-}$ collisions at the ${\rm Y}(5S)$ resonance. This sample provides ample opportunity for improving the understanding of both the properties of $B_s$ mesons and the spectroscopy of bottomonium states. In this article we describe the recent results obtained from the Belle ${\rm Y}(5S)$ data.
