Precision measurements of sin2 theta/sub W/ including the effects of radiative corrections are surveyed. A world average sin2 theta/sub W/ = 0.231 +- 0.004 is obtained. Comparison of deep-inelastic nu/sub .mu./N scattering and m/sub W/ or m/sub Z/ is shown to test the standard model at the quantum loop level and constrain new physics. Implications for extra Z' bosons and grand unified theories are briefly discussed. 25 refs., 2 figs.

The Workshop on Radiative Corrections: Results and Perspectives was held at the University of Sussex in fine weather between July 9 and 14 1989. The Workshop was weIl timed: the day after its concluding session the first beam at LEP was circulated. 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 to attempt to obtain a consensus on the best means of carrying out the calculations of the various processes. This aim became Working Group A on Renormalisation Schemes tor Electroweak Radiative Corrections. The second aim was to review the experimental implementation of radiative corrections and this became Working Group B. Here the problem was to obtain a consensus on the use of Monte Carlo event generators. At the time (March 1987) when Friedrich Dydak wrote to one of us (ND) to suggest a Workshop on the subject of electroweak radiative corrections to take place just before experiments at LEP were to begin, the main theoretical problem was that there was no agreement among theorists on the use of a specific renormalization scheme. Similarly, it was already becoming clear that it was going to be very difficult to compare the experimental results of different groups because they would use different event generators and experimental cuts of their data.

This is an expanded version of the report by the Electroweak Symmetry Breaking and Beyond the Standard Model Working Group which was contributed to Particle Physics — Perspectives and Opportunities, a report of the Division of Particles and Fields Committee for Long Term Planning. One of the Working Group's primary goals was to study the phenomenology of electroweak symmetry breaking and attempt to quantify the “physics reach” of present and future colliders. Their investigations encompassed the Standard Model — with one doublet of Higgs scalars — and approaches to physics beyond the Standard Model. These include models of low-energy supersymmetry, dynamical electroweak symmetry breaking, and a variety of extensions of the Standard Model with new particles and interactions. The Working Group also considered signals of new physics in precision measurements arising from virtual processes and examined experimental issues associated with the study of electroweak symmetry breaking and the search for new physics at present and future hadron and lepton colliders.This volume represents an important contribution to the efforts being made to advance the frontiers of particle physics.
