Implications of \Delta \rho and CHARM II data for Z' Physics

/ Authors

/ Abstract

We discuss the constraints on the Z' model parameters coming from Z- pole and low-energy \nu_{\mu}-e scattering data in the frame work of GUT- motivated models. We find that when the coupling constant of the extra U(1) is small (large) the parameter space is mainly determined by the Z-pole (the low-energy \nu_{\mu}-e scattering) data.
