Abstract

We present a direct measurement of the parity-violating asymmetry A{sub b} in the Z{sup 0} to b anti-b coupling using a new technique to distinguish the b and anti-b quarks using charged kaons from B decays. The Z{sup 0} bosons are produced in e{sup +}e{sup -} collisions at the SLC with longitudinally polarized electrons. b anti-b events are selected using a secondary vertex mass tag and A{sub b} is determined from the left-right forward-backward asymmetry. From the 1994-1995 data sample, selected from 100,000 hadronic Z{sup 0} decays, we obtain A{sub b} = 0.855 {+-} 0. 088{sub stat} {+-} 0.102{sub sys}.

Measurement of Ab from the Left-Right Forward-Backward Asymmetry in Z0 Decays using Charged Kaon Tagging

Technical Report Abe, K

We present a direct measurement of the parity violating parameter A{sub b} by analyzing the left right forward backward asymmetry of b quarks in polarized Z{sup 0} decays with a final state kaon charge tag. The 1994-1995 SLD data sample of 100,000 hadronic Z{sup 0} decays produced with a highly polarized electron beam is used for this analysis. A b-enriched sample is obtained from a vertex mass tag using a CCD based vertex detector. The b quark charge is assigned on the basis of the charge of a kaon from the B decay cascade. The charged kaon is identified bymore »« less

Preliminary measurements of the time dependence of B{sub d}{sup 0} - {bar B}{sub d}{sup 0} mixing with kaon and charge dipole tags

Conference

We report two preliminary measurements of the time dependence of B{sub d}{sup 0}- B{sub d}{sup 0} mixing using novel techniques with a sample of 150,000 hadronic Z{sup O} decays collected by the SLD experiment at the SLC. B decay vertices are reconstructed inclusively with a topological technique and the B hadron flavor at production is determined by exploiting the large left-right forward-backward asymmetry of Z{sup O} {r_arrow} b {bar b} decays in combination with a jet charge technique. Two methods are used to tag the B flavor at decay. The first uses the charge of kaons attached to the Bmore »« less

Measurement of Ab and Ac at the Z0 Resonance using a Lepton Tag

Technical Report Abe, K

The parity violation parameters of Zb{bar b} and Zc{bar c} couplings have been measured using the polar angle dependency of the Z{sup 0}-pole polarized cross section and tagging the bottom and charmed hadrons in the semileptonic decay channel. Both the muon and electron identification algorithms take advantage of multivariate techniques, incorporating information from the SLD Cerenkov Ring Imaging Detector. Based on the 1993-95 SLD samples of 50,000 Z{sup 0} decays with a mean electron beam polarization of <P{sub e}> = 63%, and 100,000 Z{sup 0} decays with a mean electron beam polarization of <P{sub e}> = 77%, this yields themore »« less
