Impact of the W boson decay width on photon bremsstrahlung accompanying W pair production
arXiv:hep-ph/0007189 · doi:10.1007/s100520000515
Abstract
The bremsstrahlung spectrum of photons accompanying pair production depends on the decay width of the unstable bosons. The dependence arises from the interference between emission at different stages of the production and decay process. We present a quantitative discussion of this effect, and consider the implications for measurements at LEP2 and LC energies.
