Summary of the Electroweak and Beyond the Standard Model Working Group

The production and study of particles through deep inelastic scattering is one of the main tools in high energy physics and has led to a comprehensive understanding of the fundamental particles and interactions up to the electroweak energy scale. Successful running of the HERA ep collider, √ s = 319 GeV, has recently come to an end, and selected results are already available from the complete 1 fb data set. The Tevatron continues to collide protons and antiprotons at √ s = 1.96 TeV, with new analyses based on up to 3 fb of data. Later this year the LHC will ramp up proton beams to √ s = 10 TeV, to be followed next year by √ s = 14 TeV pp collisions. In addition, data from the completed NuTeV fixed– target incident–neutrino experiment have been further analysed to test several hypotheses for the source of the long–standing sin θW discrepancy.
