Limits on anomalous trilinear gauge boson couplings from WW, WZ and Wγ production in pp collisions at √ s = 1.96 TeV

We present searches for the anomalous γWW and ZWW trilinear gauge boson couplings from WW and W Z production using lepton plus dijet final states and a combination with results from Wγ , WW, and W Z production with leptonic final states. The analyzed data correspond to up to 8.6 fb−1 of integrated luminosity collected by the D0 detector in p¯p collisions at √ s = 1.96 TeV. We set the most stringent limits at a hadron collider to date assuming two different relations between the anomalous coupling parameters κγ , λ, and g Z 1 for a cutoff energy scale Λ = 2 TeV. The combined 68% C.L. limits are −0.057< κγ < 0.154, −0.015 < λ < 0.028, and −0.008< g Z 1 < 0.054 for the LEP parameterization, and −0.007< κ < 0.081 and −0.017 < λ < 0.028 for the equal couplings parameterization. We also present the most stringent limits of the W boson magnetic dipole and electric quadrupole moments.
