GAUGE-INVARIANT YFS EXPONENTIATION OF (UN)STABLE W- PRODUCTION AT ANDBEYOND CERN LEP 2 ENERGIES(W)

We present the theoretical basis and sample Monte Carlo data for the Y FS exponentiated calculation of e(+)e(-)-->W+W---><f(1)(f)over bar (1) '> + <(f)over bar (2)f'(2)> at and beyond CERN LEP 2 energies, where t he left-handed parts of f(1) and f(i)' are the respective upper and lo wer components of an SU(2)(L) doublet, i=1,2. The problem of gauge inv ariance of the radiation from the unstable charged spin 1 W-+/- is sol ved in an entirely physical manner. Our formulas are illustrated in a prototypical YFS Monte Carlo event generator YFSWW2, wherein both stan dard model and anomalous triple gauge boson couplings are allowed.
