Diboson Production and Couplings
نویسنده
چکیده
s = 1.96 TeV at the Fermilab Tevatron in final states with two or three leptons, respectively, along with limits on WWZ triple gauge couplings. We also present the combined search for WW and WZ production in the lepton, neutrino, and dijet final state. Finally, we present ZZ cross section measurements in both the fully leptonic and the two lepton, two neutrino final states along with limits on anomalous couplings ZZZ and ZZγ. All results presented are based on data collected with the Run II DØ and CDF II detectors.

Diboson Physics at CDF
At the Fermilab Tevatron, the CDF detector is used to study diboson production in pp̄ collisions at √ s = 1.96 TeV. We report recent diboson production measurements, limits on anomalous triple gauge couplings and latest results from semi-leptonic diboson searches.
متن کاملDiboson Physics at the Tevatron
Tevatron diboson measurements are reviewed, and new or recent results reported for Wγ, Zγ and ZZ production in the leptonic decay modes, and for WW/WZ production in the lepton plus jets decay mode. The most stringent limits on anomalous triple gauge couplings are reported for each final state.
متن کاملDiboson Physics at the Tevatron
At the Fermilab Tevatron, the CDF and DØ detectors are used to study diboson production in p¯ p collisions at √ s = 1.96 TeV. We summarize recent measurements of the W γ, Zγ, and W W cross sections and limits on W Z and ZZ production. Limits on anomalous trilinear gauge couplings are also presented.
متن کاملDiboson production at the LHC with the CMS detector
The measurement of diboson production cross sections for a center-of-mass energy of 7 TeV is presented. Luminosities used are 1.1 fb −1 from 2011 data for ZZ, WZ and WW processes and 36 pb −1 from 2010 data for Wγ and Zγ final states. Cross sections are measured to σ (pp → ZZ + X) = 3.8 The production cross sections of processes including photons in the final state, Wγ and Zγ processes are give...
متن کاملDiboson Production at D 0
We present recent diboson production measurements from the D0 experiment at Fermilab's Teva-tron collider. The production of ZZ was observed using leptonic final states. Zγ → ννγ was observed and used to set the most stringent limits from a hadron collider on anomalous Zγγ and ZZγ trilinear gauge couplings (TGCs). WW events with leptonic final states and WW +W Z events with semi-leptonic final ...
