Measuring Chiral Parameters in the Strongly Interacting W system at a Linear Collider

Original · EN

In the absence of a Higgs particle vector boson scattering amplitudes are generally described by an electroweak chiral Lagrangian below the resonance region. For a Linear Collider with CMS energy √s=1.6 TeV and an integrated luminosity of 200 fb⁻¹ we estimate the sensitivity on the chiral parameters α₄ and α₅. We consider the processes e+e-→ W+W-νν and e+e- → ZZνν, performing a complete calculation which includes all relevant Feynman diagrams at tree level, without relying on the Equivalence Theorem or the Effective W Approximation. The dominant backgrounds and W/Z misidentification probabilities are accounted for.
