Studies of WW and WZ production and limits on anomalous WWγ and WWZ couplings

Abstract

Evidence of anomalous WW and WZ production was sought in pp̅ collisions at a center-of-mass energy of √s=1.8TeV. The final states WW(WZ)→μν jet jet+X, WZ→μνee+X and WZ→eνee+X were studied using a data sample corresponding to an integrated luminosity of approximately 90pb^-1. No evidence of anomalous diboson production was found. Limits were set on anomalous WWγ and WWZ couplings and were combined with our previous results. The combined 95% confidence level anomalous coupling limits for Λ=2TeV are -0.25≤Δκ≤0.39 (λ=0) and -0.18≤λ≤0.19 (Δκ=0), assuming the WWγ couplings are equal to the WWZ couplings.
