Abstract

Recent rate measurements of Bs mesons and Lambdab baryons produced in sqrts = 1.96 TeV proton-antiproton and Upsilon(5S) electron-positron collisions are reviewed, including the first observations of six new decay modes: Bs -> Ds+ K- (CDF), Bs -> Ds- Ds+ (CDF), Bs -> Ds1-(2536) mu+ numu X (DZero), Bs -> phi gamma (Belle), Lambdab -> p pi- (CDF), and Lambdab -> p K- (CDF). Also examined are branching-fraction measurements or limits for the Bs -> Ds(*) Ds(*) modes (Belle, CDF, and DZero), the Bs -> gamma gamma radiative penguin decay (Belle), and three two-body charmless Bs meson decay channels (CDF). Implications for the phenomenology of electroweak and QCD physics, as well as searches for physics beyond the Standard Model, are identified where applicable.
