The WWγ triple gauge boson coupling parameters are studied using pp-bar→ℓνγ+X(ℓ=e,μ) events at s√=1.96 TeV. The data were collected with the D0 detector from an integrated luminosity of 162 pb(−1) delivered by the Fermilab Tevatron Collider. The cross section times branching fraction for pp-bar→W(γ)+X→ℓνγ+X with E(γ)(T)>8 GeV and ΔR(ℓγ)> 0.7 is 14.8±1.6(stat)±1.0(syst)±1.0(lum) pb. The one-dimensional 95% confidence level limits on anomalous couplings are −0.88<Δ(κγ)<0.96 and −0.20<λ(γ)<0.20.
