Abstract
I review the new physics sensitivity of low-energy parity-violating (PV) observables. I concentrate on signatures of new tree-level physics in atomic PV with a single isotope, ratios of atomic PV observables, and PV electron scattering. In addition to comparing the new physics sensitivities of these observables with those of high-energy colliders, I also discuss the theoretical issues involved in the extraction of new physics limits from low-energy PV observables.
