Evidence for Bs production at the Upsilon(5S) from CLEO and properties of the Upsilon(4S) from BaBar
J. C. Wang
Abstract
BaBar experiment scan around the Upsilon(4S) resonance and measure its mass and full width. They also measure Br(Upsilon(4S) -> B0 B0b) = 0.486 +/- 0.010 +/- 0.009 from 81.7 fb-1 Upsilon(4S) data. CLEO collaboration took about 0.42 fb-1 Upsilon(5S) data. They search for Bs in both inclusive and exclusive modes and find evidence for Bs production at the Υ(5S) and Br(Upsilon(5S) -> Bs(*) Bs(*)b) = (21 +/- 3 +/- 9)%.
