Measurement of W-Photon Couplings in p- p¯ Collisions at s=1.8 TeV

We report on a study of $W+$ photon production in approximately 20 pb^-1 of p-p̄ collisions at √s0ex0ex=0ex0ex1.8 TeV recorded with the Collider Detector at Fermilab. Our results are in good agreement with standard model expectations and are used to obtain limits on anomalous CP-conserving WWγ couplings of -2.3<Δκ<2.2 for λ0ex0ex=0ex0ex0 and -0.7<λ<0.7 for Δκ0ex0ex=0ex0ex0 at 95% C.L. We obtain the same limits for CP-violating couplings. These results provide limits on the higher-order electromagnetic moments of the W boson of 0.8<gW<3.1 for qWᵉ0ex0ex=0ex0ex1 and -0.6<qWᵉ<2.7 for gW0ex0ex=0ex0ex2 at 95% C.L.
