Parity-violating electron scattering at Jefferson Lab
In this talk I will present a review of recent and future parity-violating electron scattering experiments at Jefferson Lab. This is a rich program of experiments to measure nuclear and nucleon properties and to search for physics beyond the Standard Model. Topics include measurements of the strange quark content of the nucleon (G0 and HAPPEX), the neutron skin of heavy nuclei (PREX and CREX) and extremely precise Standard Model tests (Qweak and MOLLER). Other experiments will measure the axial electroweak quark couplings (C2u, C2d) and search for charge symmetry violation and higher twist effects (PVDIS and others using SOLID). Jefferson Lab is capable of producing high current, high quality, highly-polarized beam which allows for small statistical and systematic uncertainties, making it an ideal place to perform these measurements. I will present a summary of the various physics goals and the general experimental considerations in parity-violating electron scattering experiments.
