Because the weak force does not conserve parity, measurement of parity violation in electron scattering provide a fertile field from which we can learn about the weak force and the Standard Model. In particular, the measurement of Parity Violation in Deep Inelastic Scattering (PVDIS) was fundamental in confirming what we now know as the Standard Model. Explicitly, PVIDS is sensitive to the effect weak couplings known as C1q and C2q. While the C1qs have been measured elsewhere, the C2qs are uniquely accessible through PVDIS. Using a 6 GeV electron beam at JLab, we have measured the C2q coefficients and shown that vector-electron, axial vector-quark coupling does, indeed, have a parity preference.
