Direct limits are set on WWZ and WW three-boson couplings in a search for WW and WZ production with high transverse momentum in pp» collisions at s=1.8 TeV, using the Collider Detector at Fermilab. The results are in agreement with the SU(2) × U(1) model of electroweak interactions. Assuming standard model WW couplings, the limits are interpreted as direct evidence for a nonzero WWZ coupling at subprocess energies near 500 GeV. Alternatively, assuming identical WWZ and WW couplings, bounds -0.11< <2.27 and -0.81< <0.84 are obtained at 95% C.L. for a form factor scale 1000 GeV. © 1995 The American Physical Society.
