Abstract
Limits on anomalous WWγ and WWZ couplings are presented from a study of WW/WZ→eνjj 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 WWγ and WWZ couplings. With the assumption that the WWγ and WWZ couplings are equal, we obtain -0.34<λ<0.36 (with Δκ=0) and -0.43<Δκ<0.59 (with λ=0) at the 95% confidence level for a form-factor scale Λ=2.0 TeV.
