Improved search for $B^0_s-\overline{B}^0_s$ oscillations / ALEPH Collaboration
An improved search for Bs oscillations is performed in the ALEPH data sample collected during the first phase of LEP, and reprocessed in 1998. Three analyses based on complementary event selections are presented. [...]

Study of $B^0_s$ oscillations and lifetime using fully reconstructed $D^-_s$ decays / ALEPH Collaboration
A search for B0s oscillations is performed using approximately 4 million Z --> qqbar events collected by the ALEPH experiment during 1991-1995. B0s candidates are partially reconstructed by combining tracks with fully reconstructed Ds- candidates. [...]

Study of the B$_{s}^{0}\overline{B}_{s}^{0}$ oscillation frequency using D$_{s}^{-}$l$^{+}$ combinations in Z decays / ALEPH Collaboration
A lower limit on the oscillation frequency of the BsBsbar system is obtained from approximately four million hadronic Z decays accumulated using the ALEPH detector at LEP from 1991 to 1995. Leptons are combined with opposite sign Ds- candidates reconstructed in seven different decay modes as evidence of semileptonic Bs decays [...]

Measurement of the Forward-Backward Asymmetry in $Z \to b\overline{b}$ and $Z \to c\overline{c}$ Decays with Leptons / ALEPH Collaboration
The sample of hadronic Z decays collected by the ALEPH detector at LEP in the years 1991-1995 is analysed in order to measure the forward-backward asymmetry in $Z \to b\bar{b}$ and $Z \to c\bar{c}$ events and the $B^0-\bar{B^0}$ average mixing parameter $\bar{\chi}$. Quark charges are tagged by the charges of electrons and muons produced in b and c semileptonic decays. [...]

Measurement of the B$^{0}_{s}$ lifetime and production rate with D$^{-}_{s}$ l$^{+}$ combinations in Z decays / ALEPH Collaboration
The lifetime of the \bs meson is measured in approximately 3 million hadronic Z decays accumulated using the ALEPH detector at LEP from 1991 to 1994. Seven different \ds decay modes were reconstructed and combined with an opposite sign lepton as evidence of semileptonic \bs decays. [...]

Investigation of Inclusive CP Asymmetries in B$^{0}$ Decays / ALEPH Collaboration
A search for CP violating effects in the mixing of neutral B mesons is performed using a sample of 4.1 million hadronic Z decays collected with the ALEPH detector from 1991 to 1995. By studying time-dependent asymmetries in flavour-tagged samples of semileptonic and fully inclusive b-hadron decays, two measurements of the semileptonic asymmetry a_cp are extracted. [...]

A study of the decay width difference in the $B^{0}_{s}-\overline{B}^{0}_{s}$ system using $\phi\phi$ correlations / ALEPH Collaboration
In a data sample of about four million hadronic Z decays recorded with the ALEPH detector from 1991 to 1995, the $B^{0}_{s} \to D^{(*)+}_{s}D^{(*)-}_{s}$ decay is observed, based on tagging the nal state with two $\phi$ mesons in the same hemisphere. The $D^{(*)+}_{s}D^{(*)-} _{s}$ final state is mostly CP even and corresponds to the short-lived $B^0$ mass eigenstate. [...]

Measurement of $\Lambda_{b}$ polarization in Z decays / ALEPH Collaboration
The \Lambda_{\mathrm{b}} polarization in hadronic \mathrm{Z} decays is measured in semileptonic decays from the average energies of the charged lepton and the neutrino. In a data sample of approximately 3 million hadronic \mathrm{Z} decays collected by the ALEPH detector at LEP between 1991 and 1994, 462\pm 31 \Lambda_{\mathrm{b}} candidates are selected using (\Lambda \pi^+)--lepton correlations.

Measurement of the b forward-backward asymmetry and mixing using high-p$_{\perp}$ leptons / ALEPH Collaboration
The B0-B0# average mixing parameter chi and b forward-backward asymmetry are measured from a sample of 4,200,000 Z -> q qbar events recorded with the ALEPH detector at LEP in the years 1990-1995. High transverse momentum electrons and muons produced in b semileptonic decays provide the tag of the quark flavour and of its charge. [...]
