Born-form approximation and full one-loop results for e+e- --> W+W- --> 4 fermions (+γ)
Masaaki Kuroda, Dieter Schildknecht
Abstract
We review the results on representing the differential cross section for W-pair produciton, including W decay and hard-photon bremsstrahlung, in terms of a Born-form approximation of fairly simple analytic form. The result of the Born-form approximation are compared with full-one-loop results. The emphasis is on the energy range of future e+e- (or μ+μ-) colliders.
