Nucleon structure study using parity violation in deep inelastic scattering with SoLID

Measurements of parity-violating asymmetries in Deep Inelastic Scattering (PVDIS) was used as a powerful tool to establish the Electroweak standard model of particle physics in the 1970's. Recently, it has also been used to search for physics beyond the Standard Model. In this talk, I will present the potential of PVDIS for the nucleon spin structure study with SoLID. In particular, scattering of an unpolarized electron beam off a longitudinally polarized target is parity-violating and will provide us a new series of $\gamma Z$ interference structure functions. These new structure functions have different flavor compositions from the parity conserving spin structure functions. They can be used as a clean method to extract flavor-separated polarized PDFs.
