Book Description
We present a preliminary result from a search for anomalous WW and WZ production in p[bar p] collisions at[radical]s= 1.8 TeV using p[bar p][yields] e[nu]jj events observed during the 1992-1993 run of the Fermilab Tevatron collider. A fit to the p[sub T] spectrum of W(e[nu]) yields direct limits on the CP-conserving anomalous WW[gamma] and WWZ coupling parameters of -0.89

Book Description
A search for anomalous WW and WZ production in p{anti p} collisions at √s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p{anti p} → e?jjX events corresponding to an integrated luminosity of 76.5 ± 4.1pb{sup −1}. 399 candidate events were identified, from which 387.1 ± 39.8 events were estimated to be background. No deviations from the Standard Model were seen, which predicts 16.2 ± 2.7 events. The 95% CL limit on the cross section?(p{anti p} → WW{sup −}X) was calculated to be 93.8 pb. Limits on the CP-conserving anomalous WW{sub?} and WWZ coupling parameters were obtained from a binned likelihood fit to the transverse momentum spectrum of the W boson. Assuming that the WW{sub?} and WWZ coupling parameters are equal, the 95% CL limits on the CP-conserving couplings are −0.56

Book Description
The search for WW and WZ production in p[anti p] collisions at[radical]s= 1.8 TeV using the CDF and D0 detectors is presented. Three analyses, one concentrating on the leptons+ jets decay channels and two concentrating on the dilepton decay channels are described in detail. Limits on anomalous WW[gamma] and WWZ trilinear gauge boson couplings are presented. Prospects for further study of diboson production and anomalous couplings with the Upgraded Tevatron are also presented.

Book Description
This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton-proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet. The data, collected at sqrt(s) =8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 inverse femtobarns. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: lambda ([-0.011,0.011]), Delta kappa[gamma] ([-0.044,0.063]), and Delta g[1,Z] ([-0.0087,0.024]). These limits are also translated into their effective field theory equivalents: c[WWW]/ Lambda^2, ([-2.7,2.7] TeV^{-2}), c[B]/ Lambda^2, ([-14,17] TeV^{-2}), and c[W]/ Lambda^2, ([-2.0,5.7] TeV^{-2}).
