Abstract
Using 420 pb(-1) of data collected on the Upsilon(5S) resonance with the CLEO III detector, we reconstruct B mesons in 25 exclusive decay channels to measure or set upper limits on the decay rate of Upsilon(5S) into B meson final states. We measure the inclusive B cross section to be sigma(Upsilon(5S)-> BB(X))=(0.177 +/- 0.030 +/- 0.016) nb and make the first measurements of the production rates of sigma(Upsilon(5S)-> (BB*)-B-*)=(0.131 +/- 0.025 +/- 0.014) nb and sigma(Upsilon(5S)-> BB*)=(0.043 +/- 0.016 +/- 0.006) nb, respectively. We set 90% confidence level limits of sigma(Upsilon(5S)-> BB)< 0.038 nb, sigma(Upsilon(5S)-> B((*))B((*))pi)< 0.055 nb and sigma(Upsilon(5S)-> BB pi pi)< 0.024 nb. We also extract the most precise value of the B-s(*) mass to date, M(B-s(*))=(5411.7 +/- 1.6 +/- 0.6) MeV/c(2).
