B physics at SLD: B(sup +) and B(sub d)(sup 0) lifetimes, B(sub s)(sup 0) mixing and search for b (r-arrow) sg decays

摘要

The authors report new preliminary B Physics results obtained with 300,000 hadronic Z(sup 0) decays collected by the SLD experiment at the SLC between 1993 and 1997. Three analyses are presented: a measurement of B(sup +) and B(sub d)(sup 0) lifetimes, a study of the time dependence of B(sub s)(sup 0)- (anti B)(sub s)(sup 0) mixing, and a search for decays of the type b (r-arrow) sg. All analyses benefit from the small and stable interaction point and the excellent resolution and efficiency provided by the pixel-based CCD Vertex Detector. The b (r-arrow) sg analysis also exploits the particle identification capabilities of the Cherenkov Ring Imaging Detector.
