TL;DR: In this paper, the production of final states involving one or more energetic photons from e+e− collisions is studied in a sample of 58.5 pb −1 of data recorded at a centre-of-mass energy of 183 GeV by the ALEPH detector at LEP.

TL;DR: In this paper, the triple gauge-boson couplings, αWΦ, α W and αBΦ have been measured using 34 semileptonically and 54 hadronically decaying W+W− candidate events.

TL;DR: In this paper, the ALEPH experiment at LEP at center-of-mass energies around 183 GeV is analyzed to search for sleptons, the partners of leptons in supersymmetric theories.

TL;DR: In this article, the ALEPH detector has been used to search for scalar top, scalar bottom and degenerate scalar quarks with data collected at LEP at s = 181-184 GeV.

TL;DR: The mass of the W boson was obtained from reconstructed invariant mass distributions in W-pair events in this paper, where the sample of W pairs was selected from 10.65~pb$^{-1}$ collected with the ALEPH detector at a mean centre-of-mass energy of 172.09 \GEV.

TL;DR: In this article, a study of events with photons and missing energy has been performed with the data sample obtained with the ALEPH detector at centre-of-mass energies from 161 to 184 GeV, corresponding to a total integrated luminosity of about 80 pb**-1.30

TL;DR: In this paper, the data collected by ALEPH at LEP at center-of-mass energies ranging from 181 to 184 GeV, corresponding to an integrated luminosity of 57 pb(-1), are analysed to search for pair-produced neutral Higgs bosons h and A, in the b (b) over bar b(b, over bar and tau(+)tau(-)b (b), over bar final states.

TL;DR: In this article, the four jet topology is analyzed in the ALEPH data taken between November 1995 and November 1997, at center-of-mass energies ranging from 130 to 184 GeV.
