Abstract
Measurements of parity violation in electron scattering have yielded a wealth of information on the structure of the nucleon and on electroweak couplings. The upgrade of the CEBAF beam energy at Thomas Jefferson National Accelerator Facility (JLab) to a maximum of 12 GeV will expand the range of kinematics in which parity violation measurements to include significantly more of the deep inelastic scattering (DIS) region, where a new information can be obtained on many interesting topics, including charge symmetry violation, higher twist contributions to proton structure and electroweak coupling constants. These coupling constants are related to sin 2 qW in the framework of the Standard Model. To differentiate between these effects, measurements of parity violation in deep inelastic scattering (PVDIS) must be made over a large kinematic range in both xBj and Q 2 . The SOLID collaboration has proposed the construction of a new, solenoidal spectrometer to make these measurements. This talk will describe these measurements and the SOLID spectrometer.
