    Tests of the Standard Model with Electroweak Physics have been performed over many decades. In these proceedings, we present several analyses from the Tevatron involving single WW or ZZ bosons.Comment: XIX International Workshop on Deep-Inelastic Scattering and Related Subjects (DIS 2011

    Testing the Standard Model with WGamma and ZGamma at the Tevatron

    Full text link
    Results on analyses involving WGamma and ZGamma production from the CDF and D0 experiments at the Fermilab Tevatron Collider at Sqrt(s) = 1.96 TeV are presented here. Using 1-2 fb^-1 of data, cross sections, anomalous coupling limits, and the WGamma Radiation Amplitude Zero are reviewed.Comment: Parallel talk at ICHEP08, Philadelphia, USA, July 200

    Taking Global Scale Data Handling to the Fermilab Intensity Frontier

    Abstract. SAM is a comprehensive data management system used by the Tevatron Run II experiments with great success. The newest experiments at Fermilab, the Intensity Frontier experiments, are currently lacking such a system. In these proceedings, the advantages of using SAM for these experiments is discussed. Two improvements to SAM, namely SAMWeb and SAMfs are described. These improvements will make SAM much easier to integrate, deploy, maintain, and use

    From electron-positron collision data collected with the CLEO detector operating at CESR near \sqrt{s}=10.6 GeV, improved measurements of the branching fractions for tau decays into three explicitly identified hadrons and a neutrino are presented as {\cal B}(\tau^-\to\pi^-\pi^+\pi^-\nu_\tau)=(9.13\pm0.05\pm0.46)%, {\cal B}(\tau^-\to K^-\pi^+\pi^-\nu_\tau)=(3.84\pm0.14\pm0.38)\times10^{-3}, {\cal B}(\tau^-\to K^-K^+\pi^-\nu_\tau)=(1.55\pm0.06\pm0.09)\times10^{-3}, and {\cal B}(\tau^-\to K^-K^+K^-\nu_\tau)<3.7\times10^{-5} at 90% C.L., where the uncertainties are statistical and systematic, respectively.Comment: 10 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, to appear in Phys.

    Measurement of Exclusive B Decays to Final States Containing a Charmed Baryon

    Get PDF
    Using data collected by the CLEO detector in the Upsilon(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Lambda_c^+ p-bar n(pi), where n=0,1,2,3. We find signals in modes with one, two and three pions and an upper limit for the two body decay Lambda_c^+ pbar. We also make the first measurements of exclusive decays of B mesons to Sigma_c p-bar n(pi), where n=0,1,2. We find signals in modes with one and two pions and an upper limit for the two body decay Sigma_c p-bar. Measurements of these modes shed light on the mechanisms involved in B decays to baryons.Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PR
