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

Le résumé fourni par la source

We present searches for the anomalous γWW and ZWW trilinear gauge boson couplings from WW and WZ production using lepton plus dijet final states and a combination with results from Wγ , WW , and WZ 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 Δ κ γ , λ , and Δ g 1 Z for a cutoff energy scale Λ = 2 TeV . The combined 68% C.L. limits are − 0.057 < Δ κ γ < 0.154 , − 0.015 < λ < 0.028 , and − 0.008 < Δ g 1 Z < 0.054 for the LEP parameterization, and − 0.007 < Δ 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.
