MEASUREMENT OF THE WW-GAMMA GAUGE BOSON COUPLINGS IN P(P)OVER-BAR COLLISIONS AT ROOT-S=1.8 TEV

The WW gamma gauge boson couplings were measured using p (p) over bar --> l nu gamma + X (l = e, mu) events at root s = 1.8 TeV observed with the DO detector at the Fermilab Tevatron Collider. The signal, obtained from the data corresponding to an integrated luminosity of 13.8 pb(-1), agrees well with the standard model prediction. A fit to the photon transverse energy spectrum yields limits at the 95% confidence level on the CP-conserving anomalous coupling parameters of -1.6 < Delta kappa < 1.8 (lambda = 0) and -0.6 < lambda < 0.6 (Delta kappa = 0). Similar limits are obtained for the CP-violating coupling parameters.
