Abstract
The WWγ triple gauge boson coupling parameters are studied using pp¯→lνlvγ+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¯→W(γ)+X→lvνγ+X with ETγ>8 GeV and ΔRlγ> 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<Δκlγ<0.96 and -0.20<λ γ<0.20.
