MODEL-INDEPENDENT ANALYSIS OF THE WEAK INTERACTION IN E--N ELASTIC-SCATTERING EXPERIMENTS

We discuss what model-independent information about the parity non-conserving electron-quark neutral current interaction can be obtained in the experiments on elastic scattering of longitudinally polarized electrons on unpolarized nucleons. Two possible forms of the neutron electric form factor GEγn(q2) are used in our analysis. The interpretation of the P-odd asymmetry, measured in these experiments, in terms of electron-quark neutral current coupling constants depends on the form chosen for GEγn(q2). We note also that the polarized e--p elastic scattering experiments might be used in principle to study the q2 dependence of GEγn(q2). © 1979.
