title = "Flavor structure of the nucleon from future parity-violating electron scattering experiments",
abstract = "The measurement of parity-violation asymmetries in electron scattering provides a means of extracting the weak neutral current of the target, i.e. that current to which the Z0 couples. Because of the relation of the weak and electromagnetic currents, and because of the close relation between the proton and the neutron, such measurements could provide the basis for examining the flavor structure of the nucleon and the nucleus.",

note = "Funding Information: The weak currents of the nucleon and nuclei can potentially provide important new information about hadronic structure . Weak structure functions can be extracted from parity-violating asymmetries in electron scattering. In the case of elastic scattering from the proton, an experiment under development for CEBAF could provide complementary information to the SAMPLE experiment being mounted at MIT-Bates. These experiments will be most sensitive to the flavor singlet Dirac or charge form factor, and the Pauli or magnetic form factor, respectively. If these measurements do not yield the standard results, it will either imply that there are significant strange quark contributions to the form factors or that the assumption of the isospin symmetry of the nucleon is incorrect . Parity-violation asymmtries in deep-inelastic scattering are dominated by the ratio of the down to up quark distribution functions . These ratios have not been measured with better than 10% precision for the nucleon or nuclear targets. In the deuteron we expect this ratio to be unity independent of x to first order, and in heavier targets a deviation from the simple minded ratio based on neutron and proton numbers might shed some light on the first EMC effect .
