Abstract

The CDF and Dcircle divide detectors were fully commissioned for physics running in Run II at the Tevatron pp collider in early 2002. Since then both experiments have collected data samples corresponding to an integrated luminosity of around integral L = 200 pb(-1) at a pp centre-of-mass energy of roots = 1.96 TeV. Datasets corresponding integral L = 120 pb(-1) have been analyzed for physics so far. Recent electroweak measurements from Run II are reviewed. Cross section times branching ratio measurements (sigma (.) Br) are presented for the intermediate vector bosons (IVB's) in their leptonic decay modes: W --> lv and Z --> l(+)l(-). For the first time, a combination of the sigma (.) Br results from the CDF and Dcircle divide experiments is made; this includes using a consistent choice of the total inelastic pj5 cross section for the luminosity determinations of the two experiments. Quantities derived from these sigma (.) Br values are also updated. These include: R-l the ratio of the sigma (.) Br values for W and Z; Br(W --> lv), the leptonic branching ratio of the W; and Gamma(W), the total decay width of the W. Other measurements using events containing W and Z leptonic decays are presented, including studies that probe the QCD phenomenology of W/Z production and searches for events containing two intermediate vector bosons.
