Search for stable hadronizing squarks and gluinos in $e^{+} e^{-}$ collisions up to $\sqrt{s}$ = 209 GeV / ALEPH Collaboration
Searches for stable, hadronizing scalar quarks and gluinos are performed using the data collected with the ALEPH detector at LEP. Gluon splitting into a gluino or a squark pair is searched for at centre-of-mass energies around the Z resonance, in the e+e- -> q qbar gluino gluino and q qbar squark antisquark processes. [...]

A measurement of the gluon splitting rate into $c\overline{c}$ pairs in hadronic Z decays / ALEPH Collaboration
The rate of gluons splitting into $c \bar{c}$ pairs in hadronic $Z$ decays is measured using the data sample collected by ALEPH from 1991 to 1995. The selection is based on the identification of leptons (electrons and muons) originating from semileptonic charm decays, and on the topological properties of signal events [...]

Search for Supersymmetric Particles with R-Parity Violating Decays in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ up to 209 GeV / ALEPH Collaboration
Searches for the pair production of supersymmetric particles under the assumption that R-parity is violated via a single dominant LLEbar, LQDbar or UbarDbarDbar coupling are performed using the data collected by the ALEPH detector at LEP at centre-of-mass energies from 189 to 209GeV. The numbers of observed candidate events in the data are in agreement with the Standard Model expectation, and limits on the production cross sections and on the masses of charginos, sleptons, squarks and sneutrinos are derived..

Search for anomalous weak dipole moments of the $\tau$ lepton / ALEPH Collaboration
The anomalous weak dipole moments of the tau lepton are measured in a data sample collected by ALEPHfrom 1990 to 1995 corresponding to an integrated luminosity of 155pb-1.
