Abstract
Parity-violating asymmetries in electron scattering result from the interference of photon- and Z{sup 0}-exchange. In the 70{sup '} and 80{sup '}, they have been used to measure sin{sup 2} {theta}{sub W} and to test the Standard Model (SM). Now one can use Parity-Violation to study the inner structure of the target, and in particular its strangeness content. Experiments measuring combinations of the strange electric, magnetic and axial form-factors at various momentum transfers Q{sup 2} have been recently done or are under way. We discuss the existing results and describe the G{sup 0} experiment at Jefferson Lab which aims at determining separately these three form-factors in the momentum range Q{sup 2}=0.12 to 1.0 (GeV/c){sup 2} by doing a Rosenbluth separation on a proton target complemented by backward quasi-elastic measurements on deuterium at similar Q{sup 2} values.
