The trilinear couplings appear as the three gauge boson vertices and can be measured by studying the gauge boson pair production processes. The measurement of the coupling parameters is one of the few remaining crucial tests of the Standard Model. D0 has studied W[gamma], Z[gamma], WW, and WZ production and found no evidence of anomalous production. In this paper we review all the current results from D0 data.

Direct measurements of vector boson pair production processes and trilinear gauge boson couplings have been conducted by the CDF and D0 Collaborations. Preliminary results from searches for anomalous WW/WZ [yields] [mu][nu] jet jet and WZ [yields] eee[nu] production are presented. 95% CL anomalous coupling limits from previously published D0 results are -0.20

The D0 and CDF Collaborations measure boson pair production including W[gamma], WW, WZ, ZZ and Z[gamma] production in p[anti p] collisions at[radical]s= 1800 GeV. New results, from direct measurements, are described including W[gamma], WW, and Z[gamma] production cross sections and limits on non-Standard Model triple gauge boson couplings. The limits on anomalous WW[gamma], WWZ, Z[gamma][gamma] and ZZ[gamma] couplings are the most restrictive available. Prospects for Run II are discussed.

Direct measurements of the trilinear gauge boson couplings by the D0 collaboration at Fermilab are reported. Limits on the anomalous couplings were obtained at a 95% CL from four diboson production processes: W[gamma] production with the W boson decaying to e[nu] or[mu][nu], WW production with both of the W bosons decaying to e[nu] or[mu][nu], WW/WZ production with one W boson decaying to e[nu] and the other W or Z boson decaying to two jets, and Z[gamma] production with the Z boson decaying to ee, [mu][mu], or[nu][nu]. Limits were also obtained from a combined fit to W[gamma], WW[yields] dileptons and WW/WZ[yields] e[nu]jj data samples.

We discuss the direct measurement of the trilinear vector boson couplings in present and future collider experiments. The major goals of such experiments will be the confirmation of the Standard Model (SM) predictions and the search for signals of new physics. We review our current theoretical understanding of anomalous trilinear gauge-boson self interactions. If the energy scale of the new physics is[approx] 1 TeV, these low energy anomalous couplings are expected to be no larger than[Omicron](10[sup -2]). Constraints from high precision measurements at LEP and low energy charged and neutral current processes are critically reviewed.
