Studies of gauge boson pair production and trilinear couplings

The gauge boson pair productionprocesses W{gamma}, WW, WZ, and Z{gamma} were studied using p{bar p} collisions corresponding to an integrated luminosity of approximately 14 pb{sup {minus}1} at a center-of-mass energy of {radical} (s) =1.8 TeV. Analysis of W{gamma} production with subsequent W bosondecay to scr(l){nu} (scr(l)=e,{mu}) is reported, including a fit to the p{sub T} spectrum of the photons which leads to limits on anomalous WW{gamma} couplings. A search for WW production with subsequent decay to scr(l)scr({bar l}){nu}{bar {nu}} (scr(l)=e,{mu}) is presented, leading to an upper limit on the WW production cross section and limits on anomalous WW{gamma} and WWZ couplings. A search for high p{sub T} W bosonsin WW and WZ production is described, where one W bosondecays to an electron and a neutrino and the second W bosonor the Z bosondecays to two jets. A maximum likelihood fit to the p{sub T} spectrum of W bosonsresulted in limits on anomalous WW{gamma} and WWZ couplings. A combined fit to the three data sets which provided the tightest limits on anomalous WW{gamma} and WWZ couplings is also described. Limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings are presented from an analysis of the photonmore » E{sub T} spectrum in Z{gamma} events in the decay channels (ee, {mu}{mu}, and{nu}{nu}) of the Z boson. {copyright} {ital 1997} {ital The American Physical Society}« less
