2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/47437I give a short report on the semi-analytical approach to off-shell W pair production. In particular, I show the effects of irreducible background diagrams of the CC11 class in the differential cross-section. Further, I study the influence of potential anomalous couplings at a future linear collider and investigate the sensitivity of the forward-backward asymmetry to anomalous couplings.9 pages, LaTeX, 4 figures, uses psfig, epsf, to appear in the proceedings of the XIIth International Workshop on High Energy Physics and Quantum Field Theory, 4--10 September 1997, Samara, RussiaHigh Energy Physics - Phenomenologytext
