TL;DR: In this article, a search for new phenomena in events characterised by high jet multiplicity, no leptons (electrons or muons), and four or more jets originating from the fragmentation of b-quarks (b-jets) is presented.

TL;DR: Two-particle correlations of Lambda Lambda and pairs have been studied in multihadronic Z decays recorded with the ALEPH detector at LEP in the years from 1992 to 1995 as discussed by the authors.

TL;DR: In this paper, the B 0 B 0 oscillation was studied using almost a million hadronic Z decays collected by the ALEPH experiment at LEP, where events were selected with two leptons present, on opposite sides of the event and with high transverse momentum.

TL;DR: In this paper, the authors measured the exclusive branching fraction for a b flavoured hadron to decay to a J/ψ is BR(b→ JψX) = (1.21±0.13 (stat.)± 0.08 (syst.))%.
