The\(x = {{2P_\parallel } \mathord{\left/ {\vphantom {{2P_\parallel } {\sqrt s }}} \right. \kern-\nulldelimiterspace} {\sqrt s }}\) distributions of inclusivee+e−,\(\bar pp\) and\(ep \to h\bar h\) are investigated using the covariant Boltzmann fact

Both the topology of hadronic final states ine + e − collisions and the evolution of event shape distributions with center of mass energy depend on the total numberN of light fermion species which couple to gluons. From an analysis ofe + e − data

Results of a new determination of QCD condensates frome+e−→Isospin 1 hadrons data are given. Using a new method to analyse these data, we show that the range of values for the gluon condensate and for the four quarks condensates, compatible with

Results are presented on an investigation of photons produced in multihadronic final states frome+e− annihilation at 35 GeV and 44 GeV center of mass energies. Scalling violation between 14 and 44 GeV is observed in inclusive photon spectra. Compar

All the published data on quark pair final states in the continuum ine + e − annihilation have been analysed in a self consistent way to study the behaviour of the strong coupling constant, α S and the associated scale parameter $$\Lambda _{\overl

Published data on lepton pair and quark pair final states ine + e − annihilation have been analysed in a self consistent way to yield values for the lepton and quark weak vector and axial vector couplings. Generation universality has been tested fo

We estimate the gluon vacuum condensate α s 〈F 2〉 from thee +e−→I=1 hadron cross-section known below 2 GeV using moment sum rules ratios. We obtain α s 〈F 2〉= (3.9±1.0)10−2GeV4. We also re-evaluate the contribution of the dimension-s
