Abstract
Limits on anomalous WW gamma and WWZ couplings are presented from a study of WW/WZ-->evjj events produced in p (p) over bar collisions at root s=1.8 TeV. Results from the analysis of data collected using the DO detector during the 1993-1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992-1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous WW gamma and WWZ couplings. With the assumption that the WW gamma and WWZ couplings are equal, we obtain -0.34 < lambda < 0.36 (with Delta kappa = 0) and -0.43 < Delta kappa < 0.59 (with lambda = 0) at the 95% confidence level for a form-factor scale Lambda = 2.0 TeV.
