Abstract

A search for Bs0 oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-95. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to Bs0 mixing is obtained by identifying subsamples of events having a Bs0 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 Δms > 9.5 ps-1 at the 95% confidence limit (95% CL). Combining with the ALEPH Ds--based analyses yields Δms > 9.6 ps-1 at 95% CL.
