Abstract
The weak charge QW measured in atomic parity violation experiments can receive compensating contributions from more than one new physics source. We show explicitly that the ΔQW 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-Q2 anomaly.
