Book excerpt: A search for anomalous WW and WZ production in p[anti p] collisions at [radical]s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p[anti p] [r-arrow] e[nu]jjX events corresponding to an integrated luminosity of 76.5 [+-] 4.1pb[sup [minus]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 [sigma](p[anti p] [r-arrow] W[sup +]W[sup [minus]]X) was calculated to be 93.8 pb. Limits on the CP-conserving anomalous WW[sub [gamma]] 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 [gamma]] and WWZ coupling parameters are equal, the 95% CL limits on the CP-conserving couplings are [minus]0.56
