Abstract
AbstractWe study the possibility of fingerprinting a strongly interactingWboson 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 theϕ∓are the azimuthal angles of decay leptons, and find that it is a useful discriminant.
Highlights
In most of the phenomenological studies of scenarios without a light Higgs boson, the onset of strong interactions among the gauge bosons is viewed in a fashion very similar to that of the strong interaction dynamics of pions

While pions are considered as the pseudo Goldstone Bosons of chiral symmetry breaking in low energy QCD, the longitudinal modes of the weak gauge bosons are essentially the Goldstone modes of electroweak symmetry breaking (EWSB)
Summary
The process e+e− → W +W − in the SM proceeds through the s-channel exchange of γ and Z, and a t-channel ν exchange, as shown in figure 1. The Omnes function, Ω(s) describes the effect of the vector resonance arising in the strong interaction of the final state W ’s. We treat GS and BW parametrizations as low energy representation of the form factor only to generate δ To contrast these effects we tabulate explicitly the values due to GS and BW parametrizations, and the corresponding Omnes function for the energies of interest given Mρ (and Γρ).
