A new Silicon Vertex Detector was developed for the ALEPH experiment and first installed for the high energy run at 130 GeV at the end of 1995. The detector has an active length of 40 cm and consists of two concentric layers of silicon wafers with double-sided readout. It extends the angular coverage, has only half the passive material as the former detector in the tracking volume and is radiation hard to cope with the higher level of radiation background expected for the LEP2 phase. The construction and the performance of the detector is described.

Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative and non-perturbative aspects of strong interactions to be carried out using hadronic Z and tau decays. The studies presented include precise determinations of the strong coupling constant, tests of its flavour independence, tests of the SU(3) gauge structure of QCD, study of coherence effects, and measurements of single-particle inclusive distributions and two-particle correlations for many identified baryons and mesons. © 1998 Elsevier Science B.V.

Two samples of exclusive semileptonic decays, 579 B̄0 → D*+ℓ-v̄ℓ events and 261 B̄0 → D+ℓ-v̄ℓ events, are selected from approximately 3.9 million hadronic Z decays collected by the ALEPH detector at LEP. From the reconstructed differential decay rate of each sample, the product of the hadronic form factor ℱ(ω) at zero recoil of the D(*)+ meson and the CKM matrix element |Vcb| are measured to be ℱD*+(1)|Vcb| = (31.9 ± 1.8stat ± 1.9syst) × 10-3, ℱD+(1)|Vcb| = (27.8 ± 6.8stat ± 6.5syst) × 10-3. The ratio of the form factors ℱD+(1) and ℱD*+ (1) is measured to be ℱD+(1)/ℱD*+ (1) = 0.87 ± 0.22stat ± 0.21syst. A value of |Vcb| is extracted from the two samples, using theoretical constraints on the slope and curvature of the hadronic form factors and their normalization at zero recoil, with the result |Vcb| = (34.4 ± 1.6stat ± 2.3syst ± 1.4th) × 10-3. The branching fractions are measured from the two integrated spectra to be Br(B̄0 → D*+ℓ-v̄ℓ) = (5.53 ± 0.26stat ± 0.52syst)%,Br(B̄0 → D+ℓ-v̄ℓ) = (2.35 ± 0.20stat ± 0.445syst)%. © 1997 Elsevier Science B.V.
