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 $209~GeV$ [...]

Search for Charged Higgs bosons: Combined Results Using LEP data / ALEPH, DELPHI, L3 and OPAL Collaborations
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments are statistically combined. [...]

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. [...]

Measurement of Z-pair production in $e^+e^−$ collisions and constraints on anomalous neutral gauge couplings / Aleph Collaboration
The ZZ production cross section is measured from a data sample corresponding to a total integrated luminosity of 452 pb−1, collected by the ALEPH experiment at LEP at centre-of-mass energies from 192 to 209 GeV. Individual cross sections, extracted at six centre-of-mass energies, are found to be in agreement with Standard Model calculations. [...]

Measurement of the Cross Section for open b-Quark Production in Two-Photon Interactions at LEP / ALEPH Collaboration
Inclusive \beauty-quark production in two-photon collisions has been measured at LEP using an integrated luminosity of $698\mathrm{pb}^{-1}\,$ collected by the ALEPH detector with $\sqrt{s}$ between 130 and 209 \GeV . The b quarks were identified using lifetime information. [...]

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 Higgs bosons decaying to WW in $e^{+}e^{-}$ collisions at LEP / ALEPH Collaboration
A search for Higgs bosons produced in association with a fermion pair, and decaying to WW, is performed with the data collected by the ALEPH detector at centre-of-mass energies ranging from 191 to 209 GeV. The data correspond to an integrated luminosity of 453.2 pb^-1. [...]

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. [...]

Test of Colour Reconnection Models using Three-Jet Events in Hadronic Z Decays / ALEPH Collaboration
Hadronic Z decays into three jets are used to test QCD models of colour reconnection (CR). A sensitive quantity is the rate of gluon jets with a gap in the particle rapidity distribution and zero jet charge. [...]
