Previously published and as yet unpublished QCD results obtained with the ALEPH detector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 …

Cross sections for e+ e−→ n-jets, as functions of the jet resolution parameter ycut, are
computed according to a new clustering algorithm. The jet multiplicity n is defined in such a …

The confinement transition from the quark and gluon degrees of freedom appropriate in
perturbation theory to the hadrons observed by real world experiments is poorly understood …

We calculate the thrust distribution in e+ e− annihilation including resummation of leading
and next-to-leading logarithms of 1− T to all orders in QCD perturbation theory. This enables …

ACCOUNTING PRINCIPLES Meeting the need for a coherently written and comprehensive
compendium combining field theory and particle physics for advanced students and …

We have studied hadronic events produced at LEP at a centre—of-mass energy of 161 GeV.
We present distributions of event shape variables, jet rates, charged particle momentum …

Bose-Einstein correlation between pairs of like-sign charged particles produced in e+ e−
annihilations near the Z0 peak have been studied using data taken with the DELPHI …

Predictions are presented for the distribution of ϱ= Mh2/s in e+ e− annihilation, where s is
the centre-of-mass energy squared and Mh is the heavy jet mass, defined as the greater if …

This paper presents an analysis of the multiplicity distributions of charged particles produced
in Z 0 hadronic decays in the DELPHI detector. It is based on a sample of 25364 events. The …

We have studied hadronic events produced at LEP at centre-of-mass energies of 130 and
136 GeV. Distributions of event shape observables, jet rates, momentum spectra and …
