Title:
Parity Violation in Leptonic DIS

Abstract:
Even in a phenomenon as familiar as parity-violating deep inelastic
scattering (PVDIS), there remains a wide range of unexplored issues, such
as effects associated with uncertainties in parton distribution functions
(PDFs), charge symmetry violation, and sensitivity to the ratio of
longitudinal to transverse cross sections at low $Q2$.  We numerically
treat these issues in the less-known context of virtual photon/Z boson
interference currents, for polarized electrons scattering from unpolarized
proton and deuteron targets, as well as unpolarized electrons and
polarized targets.  Our results are encouraging of the possibility of
extracting d quark behavior at high Bjorken x, and as such, have direct
bearing on a number of experimental proposals in  PVDIS, including those
accompanying JLab’s 12.0 GeV upgrade.
