AbstractJet properties ine+e− annihilation at center of mass energies of 14, 22, 35 and 43.7 GeV were studied with the data collected in the TASSO detector at PETRA, using the same evaluation procedures for all the energies. The total hadronic cross section ratio for the center of mass energy interval 39–47 GeV was determined to be ℛ=4.11±0.05 (stat)±0.18(syst.) at $$\langle \sqrt s \rangle = 43 - 7$$ GeV. Corrected distributions of global shape variables are presented as well as the inclusive… 

Studies of QCD at e(+)e(-) centre-of-mass energies between 91 and 209 GeV

The hadronic final states observed with the ALEPH detector at LEP in e+e- annihilation are analysed using 730 pb-1 of data collected between 91 and 209 GeV in the framework of QCD. In particular

Scaled momentum spectra in deep inelastic scattering at HERA

Charged particle production has been studied in neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 0.44 fb−1. Distributions of scaled

TLDR
The observed rise in the cross section at higher energies is consistent with the electroweak prediction for a Z-italic/sup 0/ mass of 93 GeV, and some unusual muon inclusive events are described.

Scaling violations in inclusive e + e - annihilation spectra

The origin of the observed scaling violations in inclusive e+e- annihilation is investigated. Perturbative jet evolution is not necessarily the only reason for scale breaking in the hadron spectra at
