Аннотация:The results of a search for W boson pair production in p p ̄ collisions at As51.8 TeV with subsequent decay to emu, ee, and mumu channels are presented. Five candidate events are observed with an expected background of 3.160.4 events for an integrated luminosity of approximately 97 pb-1. Limits on the anomalous couplings are obtained from a maximum likelihood fit of the E_T spectra of the leptons in the candidate events. Assuming identical WWg and WWZ couplings, the 95% C.L. limits are -0.62 < Delta{k} < 0.77 (lambda = 0) and -0.53 < lambda < 0.56 (Delta{k} = 0) for a form factor scale Lambda = 1.5 TeV.
