# Limits on anomalous WW$\gamma$ and WWZ couplings from WW/WZ $\to e\nujj$ production

Abstract : Limits on anomalous WWgamma and WWZ couplings are presented from a study of WW/WZ->enujj events in ppbar collisions at sqrt{s}=1.8 TeV. Results from the analysis of data collected using the D0 detector during the 1993-1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992-1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous WWgamma and WWZ couplings. With the assumption that the WWgamma and WWZ couplings are equal, we obtain -0.34< lambda < 0.36 (with Delta kappa=0) and -0.43< Delta kappa < 0.59 (with lambda=0) at the 95 confidence level for a form-factor scale Lambda=2.0 TeV.
