Abstract
Limits are set on anomalous WWγ and WWZ trilinear gauge couplings using W(+)W(−)→e(+)νee(−)ν¯e, W+W−→e(±)ν(e)μ(∓)ν(μ), and W(+)W(−)→μ(+)ν(μ)μ(−)ν¯(μ) events. The data set was collected by the Run II D0 detector at the Fermilab Tevatron Collider and corresponds to approximately 250 pb(−1) of integrated luminosity at s√=1.96 TeV. Under the assumption that the WWγ couplings are equal to the WWZ couplings and using a form factor scale of Λ=2.0 TeV, the combined 95% C.L. one-dimensional coupling limits from all three channels are −0.32<Δκ<0.45 and −0.29<λ<0.30.
