GAUGE-INVARIANT YFS EXPONENTIATION OF (UN)STABLE Z-PAIR PRODUCTION AND BEYOND CERN LEP-2 ENERGIES

We present the theoretical basis and sample Monte Carlo data for the Y FS exponentiated calculation of e(+)e(-)-->ZZ-->f(1) (f) over bar(1)+( f) over bar(2)f(2) at and beyond CERN LEP 2 energies, where the left-h anded part of f(i) is a component of an SU(2)(L) doublet, i=1,2. The c alculation is performed for both SM couplings and for anomalous ZZV tr iple gauge boson couplings in the conventions of Hagiwara et al. Our f ormulas, which are gauge invariant, are illustrated in a prototypical YFS Monte Carlo event generator YFSZZ. [S0056-2821(97)03823-X].
