Abstract

From data collected around the Z resonance by the OPAL detector at LEP, a sample of B-s(0) decays was obtained using D(s)(-)l(+) combinations. where the D-s(-) was fully reconstructed in the phi pi (-), K*K-0(-) and (KsK-)-K-0 decay channels or partially reconstructed in the phil(-)(nu)over bar>(X) decay channel. These events mere used to study B-s(0) oscillation. The flavor (b or (b) over bar) at decay was determined from the lepton charge while the flavor at production was determined from a combination of techniques. The expected sensitivity of the experiment is 4.1 ps(-1) The experiment was not able to resolve the oscillatory behavior. and we deduced that the B-s(0) oscillation frequency Deltam(s) > 1.0 ps(-1) at the 95% confidence level.
