Electroweak measurements from Run II at the Tevatron

The CDF and DØ detectors were fully commissioned for physics running in Run II at the Tevatron pp̄ collider in early 2002. Since then both experiments have collected data samples corresponding to an integrated luminosity of around ∫ L = 200 pb -1 at a pp̄ centre-of-mass energy of √s = 1.96 TeV. Datasets corresponding ∫ 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 (σ·Br) are presented for the intermediate vector bosons (IVB's) in their leptonic decay modes: W → ℓν and Z → ℓ +ℓ -. For the first time, a combination of the σ·Br results from the CDF and DØ experiments is made; this includes using a consistent choice of the total inelastic pp̄ cross section for the luminosity determinations of the two experiments. Quantities derived from these σ·Br values are also updated. These include: R ℓ the ratio of the σ·Br values for W and Z; Br(W → ℓν), the leptonic branching ratio of the W; and Γ 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.
