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

Authors: DURMUŞ ALİ DEMİR

Abstract: We discuss the constraints on the Z^{\prime} 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.
