Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energies at LEP / ALEPH Collaboration
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3~fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from $130~GeV$ to $209~GeV$ [...]

Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

A measurement of the Branching Ratio for the penguin decay b to s gamma, using the ALEPH detector. / Bowdery, C K ; Colrain, P ; Sloan, Terence ; Williams, M I /ALEPH Collaboration
The ALEPH data (4.1 million hadronic Z0 decays) have been analysed to search for the inclusive decay b->s gamma. This decay is sensitive to physics beyond the standard model, such as supersymmetry, through penguin diagrams. [...]

An inclusive measurement of $Br(b \to s \gamma)$ / Williams, M I (Dept of Phys, Lancaster Univ)
In a data sample of approximately four million hadronic Z/sup 0/ decays, recorded by the ALEPH detector during the years 1991 to 1995, the inclusive branching ratio for b to s gamma is measured to be: Br (b to s gamma )=(3.11+or-0.80/sub stat/+or-0.72/sub syst/)*10/sup -4 /, where the uncertainties are statistical and systematic respectively. This decay rate is consistent with that expected from standard model penguin diagrams. [...]

Search for Single Top Production in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 189 - 202 GeV / ALEPH Collaboration
The single top production via flavour changing neutral currents in the reactions ee -> t c/u is searched for in approximately 411 pb-1 of data collected by ALEPH at centre-of-mass energies in the range between 189 and 202 GeV. In total, 58 events are selected in the data to be compared with 50.3 expected from Standard Model backgrounds. [...]

Fermi-Dirac Correlations in $\Lambda$ Pairs in Hadronic Z Decays / ALEPH Collaboration
Two-particle correlations of Lambda Lambda and Anti-Lambda Anti-Lambda pairshave been studied in multihadronic Z decays recorded with the ALEPH detector at LEP in the years from 1992 to 1995. The correlations were measured as a function of the four-momentum difference Q of the pair. [...]

Bose-Einstein correlations in W-pair decays / ALEPH Collaboration
Bose-Einstein correlations are studied in semileptonicWW --> qqbarlnu and fully hadronic WW --> qqbarqqbar W-pair decays with the ALEPH detector at LEP at centre-of-mass energies of 172, 183 and 189GeV. They are compared with those made at the Z peak after correction for the different flavour compositions. [...]
