A measurement of the inclusive $b \rightarrow s \gamma$ branching ratio / ALEPH Collaboration
The flavour changing neutral current decay b -> s gamma has been detected in hadronic Z decays collected by ALEPH at LEP. The signal is isolated in lifetime-tagged b-bbar events by the presence of a hard photon associated with a system of high momentum and high rapidity hadrons. [...]

Determination of $A^{b}_{FB}$ using Jet Charge Measurements in Z Decays / ALEPH Collaboration
An improved measurement of the forward-backward asymmetry in Z-> b b-bar decays is presented, based on a sample of 4.1 million hadronic Z decays collected by Aleph between 1991 and 1995. Data are a nalysed as a function of polar angle of the event axis and b purity. [...]

Observation of doubly-charmed B decays at LEP / ALEPH Collaboration
A search for doubly-charmed B decays with both charmed mesons reconstructed is performed, using about 3.8 million hadronic Z decays recorded with the ALEPH detector at LEP. A clear signal is observed in the channels ${\mathrm B\rightarrow D_s \bar D}(X)$ and ${\mathrm B\rightarrow D \bar D}(X)$ (where D can be either a D$^0$, a D$^+$ or a D$^{*+}$), providing the first direct evidence for doubly-charmed B decays involving no ${\mathrm D_s}$ production. [...]

Search for evidence of compositeness at LEP I / ALEPH Collaboration
Extensive searches for evidence of compositeness of quarks and leptons have been made using the full set of ALEPH data from LEP running at the Z peak. They include searches for radiative and weak decays of excited leptons, and radiative and gluonic decays of excited quarks, produced either singly or in pairs. [...]

$K^{0}_{S}$ production in $\tau$ decays / ALEPH Collaboration
From a sample of about 160k $\mbox{Z}\!\!\to\!\!\tau^+\tau^-$ candidates collected with the ALEPH detector at LEP between 1991 and 1995, $\tau$ lepton decays involving $K^0_S\!\to\!\pi^+\pi^-$ are studied. The $K^0_SK^0_L$ associated production in $\tau$ decays is also investigated. [...]

Resonant structure and flavour tagging in the $B\pi^{\pm}$ system using fully reconstructed $B$ decays / ALEPH Collaboration
Starting from a sample of four million hadronic $Z$ decays collected with the ALEPH detector at LEP, 404 charged and neutral $B$ mesons are fully reconstructed and used to look for resonant structure in the $B\pi$ system. An excess of events is observed above the expected background in the $B\pi$ mass spectrum at a mass $\approx 5.7$ GeV/c$^2$, consistent with the production and decay to $B^{(*)}\pi$ of the $B^{**}$ states predicted by Heavy Quark Symmetry (HQS). [...]
