EXACT O(ALPHA) GAUGE-INVARIANT YFS EXPONENTIATED MONTE-CARLO FOR (UN)STABLE W- PRODUCTION AT AND BEYOND LEP2 ENERGIES(W)

We realize, by Monte Carlo event generator methods, the exact O(alpha) YFS exponentiated calculation of e(+)e(-) -->, W+W-(-->f(1) (f) over bar(1)' + (f) over bar(2)f(2)') at and beyond LEP2 energies, where the left-handed parts of f(i) and f(i)' are the respective upper and lowe r components of an SU2L doublet, i = 1, 2, Our calculation is gauge in variant from the standpoint of its radiative effects and the respectiv e YFS Monte Carlo event generator YFSWW3, wherein both Standard Model and anomalous triple gauge boson couplings are allowed, generates n(ga mma) radiation both from the initial state and from the final W+W-. Sa mple Monte Carlo data are illustrated. (C) 1998 Elsevier Science B.V.
