Limits on anomalous WW γ and WWZ couplings are presented from a study of WW/WZeνjj events produced in pp̅ collisions at √s = 1.8 TeV. Results from the analysis of data collected using the DØ 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 WW γ and WWZ couplings. With the assumption that the WW γ and WWZ couplings are equal, we obtain -0.34 < λ < 0.36 (with Δk=0) and -0.43< Δk<0.59 (with λ =0) at the 95% confidence level for a form-factor scale Λ = 2.0 TeV.
