2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/81982I discuss several physics issues that can be addressed through the present and future program of parity-violating electron scattering measurements. In particular, I focus on strange quark form factors, hadronic effects in electroweak radiative corrections, and physics beyond the Standard Model.To appear in proceedings of PAVI02 workshop on parity violation in electron scattering, Mainz, Germany, June 2002Nuclear Theorytext
