Limits are set on anomalous WWγ and WWZ trilinear gauge couplings using W+W- →e+vee-v̅e, W+W- →e±ve μ±v μ, and W+W- → μ+v μ μ-v̅ 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 < ΔK <0.45 and -0.29< λ <0.30.
