Query: Lepton Spectra from e^+ e^- \to W^+ W^- in the BESS model   We investigate the reaction e^+ e^- \to W^+ W^-, W^- \to l^- \bar{nu} in a
strong coupling scenario as implemented in the BESS model. Energy and angle
spectra of the secondary lepton are calculated and compared with the
predictions of the Standard Model. These spectra provide a determination of the
fraction f_0 of longitudinally polarized W's, and the backward fraction of
secondary leptons, f_{back}. Assuming BESS parameters allowed by present data,
we give numerical estimates of the effects to be expected at an e^+e^- collider
of energy \sqrt{s} = 500- 800 GeV.
