Measurements of $BR(b \to \tau^{-}\overline{\nu}_{\tau}X)$ and $BR(b \to \tau^{-}\overline{\nu}_{\tau} D^{*\pm}X)$ and Upper Limits on $BR(B^{-} \to \tau^{-}\overline{\nu}_{\tau})$ and $BR(b \to s\nu\overline{\nu})$ / ALEPH Collaboration
Inclusive branching ratios involving b to tau transitions are measured in approximately four million hadronic Z decays collected by the ALEPH detector at LEP. The fully-inclusive branching ratio b -> tau nu X and the semi-inclusive branching ratio b -> tau nu D*+/- X are measured to be (2.43 +/- 0.20 +/- 0.25)% and (0.88 +/- 0.31 +/- 0.28)%, in agreement with the standard model predictions.

Leptonic decays of the $D_s$ meson / ALEPH Collaboration
The purely leptonic decays Ds -> tau nu and Ds -> mu nu are studied in a sample of four million hadronic Z decays collected with the ALEPH detector at the LEP e+e- collider from 1991 to 1995. The branching fractions are extracted from a combination of two analyses, one optimized to select Ds -> tau nu decays with tau -> e nu nubar or mu nu nubar, and the other optimized for Ds-> mu nu decays.

Search for R-Parity Violating Production of Single Sneutrinos in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 189-209 GeV / ALEPH Collaboration
A search for single sneutrino production under the assumption that $R$-parity is violated via a single dominant $LL\bar{E}$ coupling is presented. This search considers the process ${\rm e} \gamma \;{\smash{\mathop{\rightarrow}}}\;\tilde{\nu}\ell$ and is performed using the data collected by the ALEPH detector at centre-of-mass energies from 189\,GeV up to 209\,GeV corresponding to an integrated luminosity of 637.1\,$\mathrm{pb}^{-1}$.

Study of the fragmentation of $b$ quarks into $B$ mesons at the $Z$ peak / ALEPH Collaboration
The fragmentation of b quarks into B mesons is studied with four million hadronic Z decays collected by the ALEPH experiment during the years 1991-1995. A semi-exclusive reconstruction of B->l nu D(*) decays is performed, by combining lepton candidates with fully reconstructed D(*) mesons while the neutrino energy is estimated from the missing energy of the event.

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. [...]

A Measurement of the b-quark Mass from Hadronic Z Decays / ALEPH Collaboration
Hadronic Z decay data taken with the ALEPH detector at LEP1 are used to measure the three-jet rate as well as moments of various event-shape variables. The ratios of the observables obtained from b-tagged events and from an inclusive sample are determined. [...]

Measurement of the Tau Polarisation at LEP / ALEPH Collaboration
The polarisation of $\tau$'s produced in Z decay is measured using 160 pb$^{-1}$ of data accumulated at LEP by the ALEPH detector between 1990 and 1995. The variation of the polarisation with polar angle yields the two parameters ${\cal A}_e = 0.1504 \pm 0.0068 $ and ${\cal A}_{\tau} = 0.1451 \pm 0.0059$ which are consistent with the hypothesis of $e$-$\tau$ universality.

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. Tau leptons produced in the reaction e+e- -> tau+tau- at energies close to the Z mass are studied using their semileptonic decays to pi, rho, a_1 -> pi 2pi0 or a_1 -> 3 pi. [...]
