We perform a detailed study of the process e+e-→μ+μ- νlν̄l including all contributions. The contributions other than from real gauge boson production lead to a rich phenomenology. We explore the use of the process as a means of precision measurement of the ZWW and γWW vertices. We concentrate on CERN LEP II energies, s=200 GeV, and energies appropriate to the proposed Next Linear Collider high energy e+e- collider with center of mass energies s=500 and 1 TeV. At 200 GeV, the process offers, at best, a consistency check of other processes being considered at LEP 200. At 500 GeV, the parameters κγ, λγ, κZ, and λZ can be measured to about ±0.1 or better at 95% C.L. while at 1 TeV they can be measured to about ±0.01. At the high luminosities anticipated at high energy linear colliders precision measurements are likely to be limited by systematic rather than statistical errors.
