Resumen:
The WWg triple gauge boson coupling parameters are studied using ppbar à l n g + X (l = e, m) events at sqrt(s) = 1.96 TeV. The data were collected with the D0 detector from an integrated luminosity of 162 pb-1 delivered by the Fermilab Tevatron Collider. The cross section times branching fraction for ppbar à W(g) + X à l n g + X with ETg > 8 GeV and DRlg> 0.7 is 14.8 ± 1.6(stat) ± 1.0(syst) ± 1.0(lum) pb. The one-dimensional 95% confidence level limits on anomalous couplings are -0:88 < Dkg < 0.96 and -0:20< Dlg < 0.20.
