TL;DR: In this paper, the properties of the Z resonance were measured on the basis of 190 000Z decays into fermion pairs collected with the ALEPH detector at LEP, and the forward-backward asymmetry in leptonic decays was used to determine the ratio of vector to axial-vector coupling constants of leptons.

TL;DR: In this paper, the authors presented distributions of event shape variables, jet roduction rates and charged particle momenta obtained from 53 000 hadronicZ decays, compared to the predictions of the QCD+hadronization models JETSET, ARIADNE and HERWIG, and used to optimize several model parameters.
