  • We present results from a study of pp-->Wgamma+X events utilizing data corresponding to 0.7 fb{-1} of integrated luminosity at sqrt[s]=1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider. We set limits on anomalous WWgamma couplings at the 95% C.L. The one-dimensional 95% C.L. limits are 0.49<kappa{gamma}<1.51 and -0.12<lambda{gamma}<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… CONTINUE READING

    Angles θ and φ are the polar and azimuthal angles, respectively. Pseudorapidity is defined as η = − ln [tan(θ/2)] where θ is measured with respect to the primary vertex
      Note that this NLO MC does not include the W γ final state radiation process and thus cannot be used to calculate the acceptance directly
