The parity-violating asymmetry in e-2H deep inelastic scattering (DIS) can be used to extract the weak neutral-current coupling constants C 2q . A measurement of this asymmetry at two Q 2 values is planned at Jefferson Lab. Results from this experiment will provide a value of 2C 2u - C 2d to a precision of {+-}0.03, a factor of eight improvement over our current knowledge. If all hadronic effects can be understood, this result will provide information on possible extensions of the Standard Model, complementary to other experiments dedicated to new physics searches. Presented here are the physics motivation, experimental setup, potential hadronic effects and their implications, and the future of PV DIS at Jefferson Lab.
