W gamma Production and Limits on Anomalous WW gamma Couplings in p(p)over-bar Collisions at sqrt(s)=1.96 TeV
Original language description
We measure the cross section and the difference in rapidities between photons and charged leptons for inclusive W(-} l nu) + gamma production in e gamma and mu gamma final states. Using data corresponding to an integrated luminosity of 4.2 fb(-1) collected with the D0 detector at the Fermilab Tevatron Collider, the measured cross section times branching fraction for the process p (p) over bar -} W gamma + X -} l nu gamma + X and the distribution of the charge-signed photon-lepton rapidity difference arefound to be in agreement with the standard model. These results provide the most stringent limits on anomalous WW gamma couplings for data from hadron colliders: -0.4 { Delta kappa(gamma) { 0.4 and -0.08 { lambda(gamma) { 0.07 at the 95% C.L.
