Abstract

Parity-violating electron scattering has developed into a precise and sensitive tool to probe the structure of weak neutral current interactions at Q²<< M_Z². Steady improvements in experimental techniques have made feasible asymmetry measurements with precision approaching 10 parts per billion and fractional accuracy of a few percent. In the future, upgrades of new facilities, new laboratories and further refinements of experimental techniques should allow us to explore new aspects of the strong and electroweak interactions. We describe some of these ideas in this article.
