A Combination of Preliminary Electroweak Measurements and Constraints on the Standard Model, 2002

This note presents a combination of published and preliminary electroweak results from the four LEP Collaboration and the SLD collaboration which were prepared for the 2002 winter conferences. Averages from Z resonance results are derived for hadronic and leptonic cross sections, the leptonic forward-backward asymmetries, the tau polarisation asymmetries, the bbbar and ccbar partial widths and forward-backward asymmetries and the qqbar charge asymmetry. Above the Z resonance, averages are derived for di-photon and di-fermion cross sections and forward-backward asymmetries, W-pair, Z-pair and single-W production cross section, electroweak gauge boson couplings, W mass and width and W decay branching ratios. For the first time, differential cross sections for Bhabha scattering are combined...
