摘要：

We report on a study of W + photon production in approximately 20 pb-1 of p-p collisions at s=1.8 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 WW couplings of -2.3<<2.2 for =0 and -0.7<<0.7 for =0 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 qWe=1 and -0.6<qWe<2.7 for gW=2 at 95% C.L. © 1995 The American Physical Society.
