A crucial test of the Standard Model is the measurement of electroweak gauge-boson scattering. In this paper, we describe a generic parameterization aimed at a realistic simulation of weak-boson scattering at the LHC. The parameterization implements resonances of all possible spin and isospin combinations, properly matched to the low-energy effective (chiral) Lagrangian, includes leading higher-order effects and contains a minimal unitarization scheme. We implement the parameterization in the Monte-Carlo event generator WHIZARD and present results for complete partonic cross-section integration and event generation. We provide a comparison with the effective W approximation that previously has been used for most W W scattering studies at hadron colliders.

We study collider signals for the noncommutative extension of the standard model using the Seiberg-Witten maps for SU(3) C ⊗SU(2) L ⊗ U(1) Y to first order in the noncommutativity parameters θ µν . In particular, we investigate the sensitivity of Zγ-production at the Tevatron and the LHC to the components of θ µν . We discuss the range of validity of this approximation and estimate exclusion limits from a Monte Carlo simulation. *

We discuss the non-commutative extension of the standard model constructed with the Seiberg-Witten maps for SU(3) C ⊗ SU(2) L ⊗ U(1) Y. Using the first-order approximation in the noncommutative parameters θ µν , we estimate the sensitivity of Zγ-production at the Tevatron and LHC from Monte Carlo simulation.
