Search for B0s oscillations using inclusive lepton events
ALEPH collaboration
Abstract
A search for B0s oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-1995. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to B0s mixing is obtained by identifying subsamples of events having a B0s purity which is higher than the average for the whole data sample. Unbinned maximum likelihood amplitude fits are performed to derive a lower limit of Deltams>9.5ps-1 at 95% CL. Combining with the ALEPH D-s based analyses yields Deltams>9.6ps-1 at 95% CL.
