Abstract: Measurements of parity-violating asymmetries in the scattering oflongitudinally polarized electrons off unpolarized fixed targets are used to access leptonic and semi-leptonic weak neutral current amplitudes. One thrust of the current program is the measurement the elasticneutral weak amplitude at very low $Q^2$ from scattering off a heavy spinlessnucleus, which is sensitive to the presence of a neutron skin.A second major thrust is the neutral current elastic amplitude at very low $Q^2$ off protons and electrons and in the DIS regime off deuterium, which allows precision measurements of the weak mixing angle at low energy and is thus sensitive to new physics beyond the Standard Model.
