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 ${\mathrm{pb}}^{-1\mathrm{}}$ of $p-\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}$ 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 $\mathrm{CP}$-conserving $\mathrm{WW}\gamma$ couplings of $-2.3<\Delta \kappa <2.2\mathrm{}$ for $\lambda =0\mathrm{}$ and $-0.7<\lambda <0.7\mathrm{}$ for $\Delta \kappa =0\mathrm{}$ at 95% C.L. We obtain the same limits for $\mathrm{CP}$-violating couplings. These results provide limits on the higher-order electromagnetic moments of the $W$ boson of $0.8<\mathrm{}{g}_W<3.1\mathrm{}$ for $q_W^e=1\mathrm{}$ and $-0.6<q_W^e<2.7\mathrm{}$ for $g_W=2\mathrm{}$ at 95% C.L.
