Abstract

Decays of the Υ(5S) resonance to channels with B⁺ and B0 mesons are studied using a 23.6fb^-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. Fully reconstructed B⁺→J/ψK⁺, B0→J/ψK^*0, B⁺→D^̄0π ⁺, and B0→D^-π⁺ decays are used to obtain the charged and neutral B production rates per bb̄ event, f(B ⁺)=(72.1-3.8+3.9±5.0)% and f(B0)=(77.0-5.6+5.8±6.1)%. Assuming equal rates to B⁺ and B0 mesons in all channels produced at the Υ(5S) energy, we measure the fractions for transitions to two-body and three-body channels with B meson pairs, f(BB̄)=(5.5-0.9+1.0±0.4)%, f(BB^̄*+B^*B̄)=(13. 7±1.3±1.1)%, f(B^*B^̄ ^*)=(37.5-1.9+2.1±3.0)%, f(BB̄π)=(0.0±1. 2±0.3)%, f(BB^̄*π+B ^*B̄π)=(7.3-2.1+2.3±0.8)%, and f(B ^*B^̄*π)=(1.0-1.3+1. 4±0.4)%. The latter three fractions are obtained assuming isospin conservation.
