The current status of tests of the theory of strong interactions, quantum chromo dynamics
(QCD), with data from hadron production in e+ e− annihilation experiments is reviewed. The …

Evidence for pair production of a new particle consistent with the standard-model top quark
has been reported recently by groups studying proton-antiproton collisions at 1.8 TeV center …

The top quark, discovered at the FERMILAB TEVATRON collider in 1995, is the heaviest
known elementary particle. Today, ten years later, still relatively little is known about its …

We present the general properties of multihadron final states produced by e+ e− annihilation
at center-of-mass energies from 52 to 57 GeV in the AMY detector at the KEK collider …

Density matrix techniques in the helicity basis allow us to write down explicitly the squared
matrix elements for tree-level hadroproduction and weak decay of very heavy top quark …

The top quark is the heaviest elementary particle observed to date. Its large mass makes the
top quark an ideal laboratory to test predictions of perturbation theory concerning heavy …

A comprehensive compilation of experimental data on total hadronic cross sections, and R
ratios, in e+ e− interactions is presented. Published data from the Novosibirsk, Orsay …

All the published data on quark pair final states in the continuum in e+ e− annihilation have
been analysed in a self consistent way to study the behaviour of the strong coupling …

Results are presented on a measurement of the tt pair production cross section in pp
collisions at s= 1.8 TeV from nine independent decay channels. The data were collected by …

Three-jet events produced in e+ e− annihilations are used to provide comparisons between
quark and gluon jets. Differences between quark-induced and gluon-induced jets are …
