Unravelling the WWγ and WWZ vertices at the Linear Collider: ν̅νγ and ν̅νq̅q final states

Abstract

We perform a detailed analysis of the processes e⁺e^-→ν̅νγ and ν̅νq̅q at future linear e⁺e^- colliders and assess their sensitivity to anomalous gauge boson couplings. We consider centre of mass energies √s=350, 500 and 800 GeV. We demonstrate that significant improvements can be obtained if the phase space information for the cross sections is used maximally. At 800 GeV the parameters Δκ_γ and λ_γ can be constrained, at 95% CL, to about 0.02 and 0.01, while the parameters Δκ_Z, λ_Z and Δg₁^Z can be probed down to about 0.009, 0.002 and 0.004 respectively. The precision of these measurements is likely to be limite luminosities at these energies.
