 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 $209~GeV$ [...] CERN-PH-EP-2013-022; arXiv:1302.3415; CERN-PH-EP-2013-022.- Geneva : CERN, 2013 - 126 p. - Published in : Phys.

 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. [...] CERN-PH-EP-2009-002.- Geneva : CERN, 2009 - 14 p.
