The gauge boson pair production processes Wγ, WW, WZ, and Zγ were studied using pp̅ collisions corresponding to an integrated luminosity of approximately 14 pb^-1 at a center-of-mass energy of sqrt[s]=1.8 TeV. Analysis of Wγ production with subsequent W boson decay to lν (l=e,μ) is reported, including a fit to the p_T spectrum of the photons which leads to limits on anomalous WWγ couplings. A search for WW production with subsequent decay to ll¯νν̅ (l=e,μ) is presented, leading to an upper limit on the WW production cross section and limits on anomalous WWγ 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 WWγ and WWZ couplings. A combined fit to the three data sets which provided the tightest limits on anomalous WWγ and WWZ couplings is also described. Limits on anomalous ZZγ and Zγγ couplings are presented from an analysis of the photon E_T spectrum in Zγ events in the decay channels (ee, μμ, and νν) of the Z boson.
