Tevatron Results on Gauge Boson Couplings
Abstract
Direct measurements of the trilinear gauge boson couplings by the CDF and D0 collaborations at Fermilab are reviewed. Limits on the anomalous couplings were obtained at a 95 % CL from four diboson production processes: W-gamma production with the subsequent W boson decay to e-nu or mu-nu, WW production with both the W boson decaying to e-nu or mu-nu, WW/WZ production with one of the gauge bosons decaying leptonically and the other gauge boson decaying to two jets, and Z-gamma production with the subsequent Z boson decay to e-e, mu-mu, or nu-nu. Limits were also obtained by a combined fit to W-gamma, WW to dileptons and WW/WZ semileptonic data samples.
