Limits on WWZ and WW gamma couplings from WW and WZ production in pp-bar collisions at sqrt s=1.8TeV. Academic Article uri icon

abstract

  • 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.
