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 YFS 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-handed part of f(i) is a component of an SU(2)(L) doublet, i=1,2. The calculation is performed for both SM couplings and for anomalous ZZV triple gauge boson couplings in the conventions of Hagiwara et al. Our formulas, which are gauge invariant, are illustrated in a prototypical YFS Monte Carlo event generator YFSZZ. [S0056-2821(97)03823-X].
