Nuclear Structure Uncertainties in Parity-Violating Electron Scattering from Carbon 12

Understand

High precision measurements of the parity-violating asymmetry in polarized electron scattering from nuclei can be used to extract information on nuclear and nucleon structure or to determine Standard Model couplings and higher-order radiative corrections.

• To this end, low uncertainties are also required in the effects that inevitably arise from modeling the underlying nuclear structure.
• An experimental precision of a few tenths of a percent may be attainable for the asymmetry if the appropriate kinematic range is chosen, as will be discussed here for the case of $^{12}$C.
• And given this, the dual goal of ascertaining both the sizes of various nuclear structure related effects and of providing estimates of their uncertainties for this particular target will be discussed.
