Constraints on anomalous QGC's in $e^{+}e^{-}$ interactions from 183 to 209 GeV / ALEPH Collaboration
The acoplanar photon pairs produced in the reaction e+ e- --> nu nubar gamma gamma are analysed in the 700 inverse nanobarns 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. [...]

Measurement of the Hadronic Photon-Structure Function at LEP 1 for $l$-Angle-$Q^{2}$ $r$-Angle Values between 9.9 and 284 $GeV^{2}$ / ALEPH Collaboration
Inclusive gamma^*gamma interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of the photon F_2^gamma in three bins with <Q^2> of 9.9, 20.7 and 284 GeV^2..

Measurement of triple gauge-boson couplings at 172 GeV / ALEPH Collaboration
The triple gauge-boson couplings, Awp, Aw and Abp, have been measured using 34 semileptonically and 54 hadronically decaying WW candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb^-1. [...]

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. [...]

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. [...]

Search for a Scalar Top almost degenerate with the lightest Neutralino in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ up to 202 GeV / ALEPH Collaboration
Data collected at centre-of-mass energies from 189 GeV to 202 GeV by the ALEPH detector at LEP, corresponding to an integrated luminosity of 411 pb-1, are analysed in a search for the scalar top in the decay channels 'stop -> c/u neutralino' for small mass differences between the stop and the lightest neutralino. No evidence for deviations from the Standard Model expectation is found and a lower limit of 59 GeV/c**2 is set for the stop mass, independent of the stop to neutralino mass difference and of the stop lifetime..
