Abstract: (APS)

We discuss the effect of an extra neutral boson Z′ on atomic parity violation. Using the limit on Δρ from the Collider Detector at Fermilab and CERN LEP experiments and limits on ΔQW 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.
