Studies of gauge boson pair production and trilinear couplings

The gauge boson pair production processes W gamma, WW, WZ, and Z gamma were studied using p (p) over bar p collisions corresponding to an integrated luminosity of approximately 14 pb(-1) at a center-of-mass energy of root s = 1.8 TeV. Analysis of W gamma production with subsequent W boson decay to l nu (l = e, mu) is reported, including a fit to the p(T) spectrum of the photons which leads to limits on anomalous WW gamma couplings. A search for WW production with subsequent decay to ll nu<(nu)over bar> (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(T) W bosons in WW and WZ production is described, where one W boson decays to an electron and a neutrino and the second W boson or the Z boson decays to two jets. A maximum likelihood fit to the p(T) spectrum of W bosons resulted 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 photon E-T spectrum in Z gamma events in the decay channels (ee, mu mu, and nu nu) of the Z boson.
