Description
In this talk, an overview of parity violation deep inelastic scattering (PVDIS) future experiment by using a Solenoidal Large Intensity Device (SoLID) at Jefferson Lab (JLab) Hall A with the $12$ GeV upgrade, along with a brief description of the proposed SoLID spectrometer is discussed. We will obtain data with high statistic and large kinematic coverage for Bjorken $0.3< x <0.7$ and in the momentum transfer $2< Q^{2} <10\;(GeV/c)^{2}$ range by a polarized electron beam scattering on unpolarized deuteron and proton targets. A measurement of PVDIS in deuteron aims to extract fundamental coupling constants $C_{2q}$ as well as the weak mixing angle $sin^{2}\theta_{w}$ with a high precision. This measurement can also access QCD physics of searching for charge symmetry violation (CSV) in PDF's and higher-twist effects with quark-quark correlations. In addition, the proton target experiment can be a powerful probe of the $d/u$ ratio at high $x$ without any nuclear correction. The designed SoLID spectrometer with its unique feature of high luminosity and large acceptance provides an opportunity to probe physics beyond the Standard Model.
