摘要
We use data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of D-s mesons as B(Upsilon(5S)-> DsX)=(44.7 +/- 4.2 +/- 9.9)% and B(Upsilon(4S)-> DsX)=(18.1 +/- 0.5 +/- 2.8)%. From these measurements, we make a model dependent estimate of the ratio of B-s((*)) (B) over bar ((*))(s) to the total b (b) over bar quark pair production of (16.0 +/- 2.6 +/- 5.8)% at the Upsilon(5S) energy.
