Study of $B_{s}^{0}$ oscillations and measurement of the inclusive b semileptonic branching ratio in ALEPH

An improved search for B/sub s//sup 0/ oscillations is performed on b hadron decays collected by the ALEPH experiment during 1991-1995 with three analyses, using respectively an inclusive sample of semileptonic b decays, a sample of D/sub s//sup +/-l/sup -/ events and a sample of fully reconstructed...

description An improved search for B/sub s//sup 0/ oscillations is performed on b hadron decays collected by the ALEPH experiment during 1991-1995 with three analyses, using respectively an inclusive sample of semileptonic b decays, a sample of D/sub s//sup +/-l/sup -/ events and a sample of fully reconstructed B/sub s//sup 0/ decays. This update results in a significant improvement over previously published results. A precise measurement of the inclusive semileptonic b branching ratio is performed, by exploiting the correlation between the lepton charge and an inclusive charge estimator in the opposite hemisphere, thus allowing to reduce the dependence on the b-decay modelling. (12 refs).
