LIMITS ON MIXING ANGLE AND MASS OF Z' USING DELTA-RHO AND ATOMIC PARITY VIOLATION

We discuss the effect of an extra neutral boson Z' on atomic parity violation. Using the limit on DELTA-rho from the Collider Detector at Fermilab and CERN LEP experiments and limits on DELTA-Q(W) from the experiment of Noecker, Masterson, and Wieman on atomic parity violation, we obtain limits on the mixing angle of Z' with the canonical Z and the mass of Z'. Eleven models with an extra Z' have been analyzed. The limits obtained are comparable to the corresponding limits extracted from the Z-decay experiments at LEP.
