TL;DR: The full LEP-1 data set collected with the ALEPH detector at the Z pole during 1991-1995 is analyzed in order to measure the tau decay branching fractions as discussed by the authors.

TL;DR: In this article, the flavour changing neutral current decay b→sγ has been detected in hadronic Z decays collected by ALEPH at LEP, which is isolated in lifetime-tagged b b events by the presence of a hard photon associated with a system of high momentum and high rapidity hadrons.

TL;DR: In this paper, a new measurement of the ratio of the CP-violating amplitudes for KL → 2π0 and KL → π+π− is reported, which gives a value for the parameter describing direct CP violation: Re ϵ'/ϵ = (2.0 ± 0.7) × 10−3.

TL;DR: In this paper, it was shown that direct CP violation may also occur in the decay of K2 into two pions with a relative amplitude?′, which is non-zero in the case of a phase difference between the amplitudes A0 and A2 for the decay into isospin O and 2 states of two charged pions.

TL;DR: In this paper, the results of the four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, were combined within the Two Higgs Doublet Models (2HDMs) for Type I and Type II benchmark scenarios.
