High-Energy Cross Section for e+e- to W+ W- to 4 fermions + gamma
Abstract
A recently suggested high-energy Born-form representation of the one-loop helicity amplitudes for e+e- to W+W- is supplemented by including W+- decay and hard-photon radiation. Results for the differential and the total cross section for e+e- to W+W- to 4 fermions + gamma are given for the high-energy region of sqrt(s) > 500 GeV.
