Book cover The ALEPH "experience" : 25 years of memories / Grupen, Claus (ed.) ; Hughes, Ian (ed.) ; Lynch, James G (ed.) ; Settles, Ron (ed.)

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. [...]

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 the Michel parameters and the $\nu_{\tau}$ helicity in $\tau$ lepton decays / ALEPH Collaboration
A measurement of the Michel parameters and the average $\nu_\tau$ helicity in $\tau$ lepton decays is described. The data was collected with the ALEPH detector at LEP during the years 1991 to 1995. [...]

Search for CP violation in the decay Z --> b$\overline{b}$g / ALEPH Collaboration
About three million hadronic decays of the Z collected by ALEPH in the years 1991-1994 are used to search for anomalous CP violation beyond the Standard Model in the decay Z -> b \bar{b} g. The study is performed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-jet rate. [...]
