Abstract
The time dependence of B-d(-)(B) over bar(d)(-0) oscillations is measu red by the ALEPH experiment at LEP, using three techniques; two of whi ch are updates of previous measurements. In all cases the charge of th e decaying b quark and its decay time are measured in one hemisphere o f the event; the quark charge at production is tagged mainly using the opposite hemisphere. The first method uses the charge correlation bet ween a D(-) and a lepton in the opposite hemisphere; if no lepton is present, the produced quark charge is determined from the hemisphere c harges. In the second method, the decay time is measured using a lepto n in one hemisphere and the initial state is inferred from the opposit e-hemisphere jet charge. The third method uses a lepton in each hemisp here. The data used were collected from 1991 to 1994. The combined res ult is Delta m(d)=0.446+/-0.032 ps(-1).
