Relaxing atomic parity violation constraints on new physics
Copyright policy )Relaxing atomic parity violation constraints on new physics
The weak charge $Q_W$ measured in atomic parity violation experiments can receive compensating contributions from more than one new physics source. We show explicitly that the $��Q_W$ contribution from the exchange of an extra Z-boson can cancel that from the $s$-channel scalar top or scalar charm exchange in R-parity violating SUSY models proposed to explain the HERA high-$Q^2$ anomaly.
