Constraining Extra Neutral Gauge Bosons with Atomic Parity Violation Measurements

Abstract

The discovery of a new neutral gauge boson, $Z^{\prime }$, could provide the first concrete evidence of physics beyond the standard model. We explore how nuclear weak charge measurements in atomic parity violation (APV) experiments can be used to constrain $Z^{\prime }$ bosons. We use the recent measurement of the ${}^{133}$Cs nuclear weak charge to estimate lower bounds on the mass of $Z^{\prime }$ bosons for a number of representative models and to put constraints on the couplings of a newly discovered $Z^{\prime }$ boson. We also consider how these constraints might be improved by future APV experiments that will measure nuclear weak charges of multiple isotopes. We show how measurements of a single isotope, and combining measurements into ratios and differences, can be used to constrain the couplings of a $Z^{\prime }$ and discriminate between models. We find that current and future APV experiments could potentially play an important role in unravelling new physics if a $Z^{\prime }$ were discovered.
