The energy dependence of the relative production rate three-jet events is studied in hadronic e+e− annihilation at center mass energies between 22 and 46.7 GeV. Three-jet are defined by a jet finding algorithm which closely related to definition resolvable jets used O(αs2) perturbative QCD calculations, where roughly proportional size strong coupling strength. rates data decrease significantly with increasing centre energy. experimental rates, independent fragmentation model can be directly...
Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative non-perturbative aspects strong interactions to be carried out using hadronic Z tau decays. presented include precise determinations coupling constant, tests its flavour independence, SU(3) gauge structure QCD, study coherence effects, measurements single-particle inclusive distributions two-particle...
Two samples of exclusive semileptonic decays, 579 B0 →D∗+ℓ−νℓ events and 261 → D+ℓ−νℓ events, are selected from approximately 3.9 million hadronic Z decays collected by the ALEPH detector at LEP. From reconstructed differential decay rate each sample, product form factor F(ω) zero recoil D(∗)+ meson CKM matrix element |Vcb| measured to be FD∗+(1)|Vcb| = (31.9 ± 1.8stat 1.9syst) × 10−3, FD+(1)|Vcb| (27.8 6.8stat 6.5syst) 10−3. The ratio factors FD+(1) FD∗+(1) is FD+(1)FD∗+(1) 0.87 0.22stat...
