Deuteron and Anti-deuteron Production in $e^{+}e^{-}$ Collisions at the Z resonance / ALEPH Collaboration
Deuteron and anti-deuteron production in Z decays has been observed in the ALEPH experiment at LEP. The production rate of anti-deuterons is measured to be 5.9+-1.8+-0.5 10^-6 per hadronic Z decay in the anti-deuteron momentum range 0.62 to 1.03 GeV/c. [...]

Search for neutral Higgs bosons decaying into four taus at LEP2 / ALEPH Collaboration
A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb-1 of data collected by the ALEPH experiment at centre-of-mass energies from 183 to 209 GeV. No excess of events above background is observed, and exclusion limits are placed on the combined production cross section times branching ratio, \xi^2 = \sigma(e+e- --> Zh)/\sigma_{SM}(e+e- --> Zh) x B(h --> aa)x B(a --> \tau^+\tau^-)^2. [...]

Fermion pair production in $e^+e^-$ collisions at 189-209 GeV and constraints on physics beyond the Standard Model / ALEPH Collaboration
Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e+e-, mu+mu-, tau+tau-, qq, bb and cc production are in agreement with the Standard Model predictions. [...]

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. [...]

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.
