    Abstract
    We present results from a study of pp-bar→Wγ+X events utilizing data corresponding to 0.7  fb(−1) of integrated luminosity at s√=1.96  TeV collected by the D0 detector at the Fermilab Tevatron Collider. We set limits on anomalous WWγ couplings at the 95% C.L. The one-dimensional 95% C.L. limits are 0.49<κ(γ)<1.51 and −0.12<λ(γ)<0.13. We make the first study of the charge-signed rapidity difference between the lepton and the photon and find it to be indicative of the standard model radiation-amplitude zero in the Wγ system.
