Final-state radiative effects for the exactO(α)Yennie-Frautschi-Suura exponentiated (un)stableW+W−production at and beyond CERN LEP2 energies

We present the leading-logarithm (LL) final-state radiative effects for the exact $\mathcal{O}\left(\alpha \right)$ YFS exponentiated (un)stable $\mathrm{WW}$ pair production at CERN LEP2 or NLC energies using Monte Carlo event generator methods. The corresponding event generator, version 1.12 of the program YFSWW3, wherein both standard model and anomalous triple gauge-boson couplings are allowed, generates $n\left(\gamma \right)$ radiation both from the initial state and from the intermediate $W^{+}{W}^{-}$ state, and generates the LL final state W decay radiative effects. Sample Monte Carlo data are given for illustration.
