Description
We report on the measurement of parity-violating (PV) asymmetries in the
deep inelastic scattering (DIS) and nucleon resonance regions using
inclusive scattering of longitudinally polarized electrons off an
unpolarized deuterium target. The effective weak couplings C_2q are
accessible through the DIS measurements. Here we report a measurement
of the PV asymmetry, which yields a determination of 2C_2u - C_2d with
an improved precision of a factor of five relative to previous results.
These results indicate evidence with 95% confidence that
the 2C_2u - C_2d is non-zero. This experiment also provides the first
parity-violation data covering the whole resonance region, which provide
constraints on nucleon resonance models. Finally, the program to measure
PV-DIS at JLab in the 12 GeV era will be discussed using the Solenoidal
Large Intensity Device (SoLID).
