Abstract
We study the possibility of fingerprinting a strongly interacting W boson sector which is consistent with present day LHC searches at the ILC with longitudinal as well as transversely polarized electron and positron beams. We account for the final state interaction using a suitable Omnès formalism in terms of a plausible resonance description, and carry out thorough analyses of cross sections, asymmetries and angular distributions of the W′s. We carry out a comparison with other extensions of the Standard Model, where heavy additional Z′bosons arise naturally. We also consider the effect of the strong final state interaction on a correlation that depends on \( \left( {{\phi_{ - }} - {\phi_{ + }}} \right) \) , where the ϕ ∓ are the azimuthal angles of decay leptons, and find that it is a useful discriminant.
