EXPLORATION OF BELOW THRESHOLD Z' MASS AND COUPLING DETERMINATIONS ATTHE NLC

We examine of the capability of the Next Linear Collider to determine the mass as well as the couplings to leptons and b quarks of a new neu tral gauge boson Z' below direct production threshold. By using simula ted data collected at several different values of root s, we demonstra te how this can be done in a model-independent manner via an anonymous case approach. The importance of beam polarization to the success of this program is discussed. The procedure is shown to be easily extende d to the case of top and charm quark couplings.
