Evidence for B_s production at the Upsilon(5S) from CLEO and properties of the Upsilon(4S) from BaBar

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 B_s in both inclusive and exclusive modes and find evidence for B_s production at the Υ(5S) and Br(Upsilon(5S) -> B_s^(*) B_s^(*)b) = (21 +/- 3 +/- 9)%.
