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

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

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.

The authors present results from a search for WZ production with subsequent decay to l[nu]l'{bar l}' (l and {ell}' = e or [mu]) using 0.30 fb−1 of data collected by the D0 experiment between 2002 and 2004 at the Tevatron. Three events with WZ decay characteristics are observed. With an estimated background of 0.71 ± 0.08 events, we measure the WZ production cross section to be 4.5{sub -2.6}{sup +3.8} pb, with a 95% C.L. upper limit of 13.3 pb. The 95% C.L. limits for anomalous WWZ couplings are found to be -2.0
