Results on R from PEP, PETRA, TRISTAN, and SLCf mass energies between 7 and 93 GeV. At the highest TRISTAN energies, the tail of the .. resonance does increase . by 50%. Such a sizeable increase allows a direct measurement of ... However, this measurement turns out to be somewhat below the direct value measured at SLC at energies around the ..-

Multiple Soft Photon Bremsstrahlung on the Z Resonanceation near the . resonance. Our results are based on a modified soft photon approximation that respects the resonant character of the matrix element. Also the influence of a cutoff for the total radiated energy is investigated.

One-Loop Flavour-Changing Neutral Currents in the Standard Modelooft-Feynman gauge, and the on-shell renormalization scheme is used. The results for on-shell quarks and for the gluon and photon vertices are compared with the ones derived using the usual approximation of neglecting the external quark masses. This approximation is shown to be unreliable.

Generalized Radiative Corrections for Hadronic Targetsctro-magnetic scattering on hadronic targets remains that given in the ’60s by Y. S. Tsai. for structureless spin zero bosons. However, with the enhanced accuracy of new experimental data — the error is currently down to 1–2% on electron scattering cross sections -, and the improvements in theoretic

The Original aims of the Workshop were twofold: first to review the existing theoretical work on electroweak radiative corrections in the light of the initial experiments at SLC and LEP, and
