A study of the Standard Model (SM) three electroweak boson
production, WV$\gamma$ where V = W or Z gauge boson, is
presented concerning events with a leptonically
decaying W boson accompanied by a photon and two or more
jets. We are using the full 2012 dataset, of proton-proton
collisions at a center-of-mass energy of 8 TeV and an integrated
luminosity of 20 fb$^{-1}$,...

Measurements of the productions of final states with multiple neutral bosons with ATLAS will be reported. Using 20 fb−1 data collected by the ATLAS detector at a center-of-mass energy of 8 TeV of proton-proton collisions, the production cross sections for ZZ, Zγ and Zγγ final states are measured using events where the Z bosons decay to electron- or muon- pairs. These final states have clean...

The production cross section measurements of dibosons and tribosons with W bosons using approximately 20 inverse femtobarn data of 8 TeV p-p collisions collected by the ATLAS detector at the Large Hadron Collider are presented. These measurements are important tests of the Standard Model predictions. The final states of interest include WW, WZ, Wgamma and Wgammagamma. No significant deviations...

We present a summary of the latest measurements of the VV cross-sections, where V=W or Z and one of the bosons decays into a pair of jets while the other decays leptonically. The data sample(s) correspond to proton-proton collision events collected with the CMS detector at sqrt(s) = 7, 8 TeV. Subsequent searches for Anomalous Triple Gauge couplings, which allow us to probe the non-Abelian...

Due to its small branching ratio, the process pp̄ → Z/γ∗ Z/γ∗ → l+l−l′+l′− has one the smallest cross sections in the Standard Model (SM). However, the presence of four isolated leptons in the final state makes this process a very pure one, with a relatively small background. In this work we present a measurement of the cross section pp̄ → Z/γ∗ Z/γ∗ → l+l−l′+l′− with up to 9.8 fb−1 of data...

Beginning with the electroweak Lagrangian, the the two-body Green’s function can be written for various two body systems. For each possible two body system, the appro- priate Bethe-Salpeter equation is derived from which bound states containing any of the particles that are the constituents of the electro-weak theory. In particular, bound states with vector bosons is constituent are described...

We present a measurement of the W boson mass using data corresponding to an integrated luminosity of 4.3 fb-1 collected with the D0 detector during Run 2 at the Fermilab Tevatron ppbar collider. With a sample of 1,677,394 W--> e nu candidate events, we measure M_W = 80.367 +/- 0.026 GeV. This result is combined with an earlier D0 result determined using an independent Run 2 data sample,...

A measurement of vector boson production and the ratio of W boson
to Z boson production in association with jets using sqrt(s) = 7 TeV
p-p collisions at the LHC of the 2011 ATLAS dataset with an
integrated luminosity of 4.6 pb is presented. Inclusive and
differential cross sections and cross section ratios for the vector bosons decaying to electrons and muons are measured for jets with...
