Abstract
The weak charge Q(w) measured in atomic parity violation experiments c an receive compensating contributions from more than one new physics s ource. We show explicitly that the Delta Q(w) contribution from the ex change of an extra Z-boson can cancel that from the s-channel scalar t op or scalar charm exchange in R-parity violating SUSY models proposed to explain the DESY HERA high-Q(2) anomaly. [S0556-2821(98)50107-5].
