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. [...]

Search for pentaquark states in Z decays / ALEPH Collaboration
Exotic hadrons made of five quarks (pentaquarks) are searched for in hadronic Z decays collected by the ALEPH detector at LEP. No significant signal is observed. [...]

Constraints on anomalous QGCs in $e^{+}e^{-}$ interactions from 183 to 209 GeV / ALEPH Collaboration
The acoplanar photon pairs produced in the reaction e/sup +/e/sup to / nu nu gamma gamma are analysed in the 700 pb/sup -1/ of data collected by the ALEPH detector at centre-of-mass energies between 183 and 209 GeV. No deviation from the standard model predictions is seen in any of the distributions examined. [...]

Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

Improved measurement of the Triple-Gauge-Boson Couplings $\gamma WW$ and ZWW in $e^+ e^-$ collisions / ALEPH Collaboration
Triple gauge-boson couplings WWgamma and WWZ involving single-photon, single-W and W-pair production are determined using data samples collected at LEP with the ALEPH detector at centre-of-mass energies between 183 and 209 GeV. The integrated luminosity used is 700 pb-1 for the single-photon measurement and 683 pb-1 for the W channels. [...]

Bose-Einstein correlations in W-pair decays with an event-mixing technique / ALEPH Collaboration
Bose-Einstein correlations in W-pair decays are studied using data collected by the ALEPH detector at LEP at e+e- centre-of-mass energies from 183 to 209 GeV. The analysis is based on the comparison of WW-->qqqq events to ``mixed'' events constructed with the hadronic part of WW-->qqlnu events. [...]

Two-Particle Correlations in pp, $\overline{p}\overline{p}$ and $K^{0}_{s}K^{0}_{s}$ pairs from Hadronic Z decays / ALEPH Collaboration
Two-Particle correlations in pp, pbarpbar and K0sK0s pairs have been studied in hadronic Z decays recorded at LEP with the ALEPH detector. The correlations were measured as a function of the four-momentum difference Q of the pair. [...]
