Results from Upsilon(5S) at Belle: Strange Beauty and other Beasts

Abstract

The Belle experiment collected in 2005-6 a total of 23.6 fb${}^{-1}$ of data at the ${\rm Y}(10860)$ resonance, also known as ${\rm Y}$(5S). These constitute nearly all of the world's sample of $e^{+}{e}^{-}\to {\rm Y}$(10860) events, which provide clean $B_s$ pairs. We present here several $B_s$ and ${\rm Y}$(10860) properties recently extracted from these data.
