Description

The $\Upsilon$(5S) decays to channels with $B^+$ and $B^0$ mesons are studied using a 23.6 fb~$^{-1}$ data sample collected on the $\Upsilon$ (5S) resonance with the Belle detector at the KEKB asymmetric energy $e^+ e^-$ collider. Using fully reconstructed $B$ mesons, we measure the total $B^+$ and $B^0$ production rates per $b\bar{b}$ event and the two-body, three-body and four-body channel $\Upsilon$(5S) decay fractions for events with $B$ mesons.
