PHENOMENOLOGICAL STUDY OF THE PROCESS E--]MU+MU-NU(L)(NU)OVER-BAR(L) AT HIGH-ENERGY E+E- COLLIDERS AND MEASUREMENT OF THE ZWW AND GAMMA-WW COUPLINGS(E)

We perform a detailed study of the process e+e- --> mu+mu-nu(l)nu(l)BA R including all contributions. The contributions other than from real gauge boson production lead to a rich phenomenology. We explore the us e of the process as a means of precision measurement of the ZWW and ga mmaWW vertices. We concentrate on CERN LEP II energies, square-root s = 200 GeV, and energies appropriate to the proposed Next Linear Collid er high energy e+e- collider with center of mass energies square root s = 500 and 1 TeV. At 200 GeV, the process offers, at best, a consiste ncy check of other processes being considered at LEP 200. At 500 GeV, the parameters kappa(gamma), lambda(gamma), kappa(Z) and lambda(Z) can be measured to about +/- 0.1 or better at 95% C.L. while at 1 TeV the y can be measured to about +/-0.01. At the high luminosities anticipat ed at high energy linear colliders precision measurements are likely t o be limited by systematic rather than statistical errors.
