Limits on {ital WWZ} and {ital WW}{gamma} couplings from {ital WW} and {ital WZ} production in {ital p{bar p}} collisions at {radical}{ital s}=1.8TeV
Direct limits are set on {ital WWZ} and {ital WW}{gamma} three-boson couplings in a search for {ital WW} and {ital WZ} production with high transverse momentum in {ital p{bar p}} collisions at {radical}{ital s}=1.8 TeV, using the Collider Detector at Fermilab. The results are in agreement with the SU(2) {times} U(1) model of electroweak interactions. Assuming standard model {ital WW}{gamma} couplings, the limits are interpreted as direct evidence for a nonzero {ital WWZ} coupling at subprocess energies near 500 GeV. Alternatively, assuming identical {ital WWZ} and {ital WW}{gamma} couplings, bounds {minus}0.11{lt}{kappa}{lt}2.27 and {minus}0.81{lt}{lambda}{lt}0.84 are obtained at 95% C.L. for a form factor scale 1000 GeV.
